Main article Library classification A library classification is a system of coding and organizing library materials (books, serials, audiovisual materials, computer files, maps, manuscripts, realia) according to their subject and allocating a call number to that information resource. Similar to classification systems used in biology, bibliographic classification systems group entities together that are similar, typically arranged in a hierarchical tree structure. A different kind of classification system, called a faceted classification system, is also widely used which allows the assignment of multiple classifications to an object, enabling the classifications to be ordered in multiple ways.
Description Library classification forms part of the field of library and information science. It is a form of bibliographic classification (library classifications are used in library catalogs, while "bibliographic classification" also covers classification used in other kinds of bibliographic databases). It goes hand in hand with library (descriptive) cataloging under the rubric of cataloging and classification, sometimes grouped together as technical services. The library professional who engages in the process of cataloging and classifying library materials is called a cataloguer or catalog librarian. Library classification systems are one of the two tools used to facilitate subject access. The other consists of alphabetical indexing languages such as Thesauri and Subject Headings systems. Library classification of a piece of work consists of two steps. Firstly the "aboutness" of the material is ascertained. Next, a call number (essentially a book's address), based on the classification system in use at the particular library will be assigned to the work using the notation of the system. It is important to note that unlike subject heading or thesauri where multiple terms can be assigned to the same work, in library classification systems, each work can only be placed in one class. This is due to shelving purposes: A book can have only one physical place. However in classified catalogs one may have main entries as well as added entries. Most classification systems like the Dewey Decimal Classification (DDC) and Library of Congress classification also add a cutter number to each work which adds a code for the author of the work. Classification systems in libraries generally play two roles. Firstly they facilitate subject access by allowing the user to find out what works or documents the library has on a certain subject.[1] Secondly, they provide a known location for the information source to be located (e.g. where it is shelved). Until the 19th century, most libraries had closed stacks, so the library classification only served to organize the subject catalog. In the 20th century, libraries opened their stacks to the public and started to shelve the library material itself according to some library classification to simplify subject browsing. Some classification systems are more suitable for aiding subject access, rather than for shelf location. For example, UDC which uses a complicated notation including plus, colons are more difficult to use for the purpose of shelf arrangement but are more expressive compared to DDC in terms of showing relationships between subjects. Similarly faceted classification schemes are more difficult to use for shelf arrangement, unless the user has knowledge of the citation order. Depending on the size of the library collection, some libraries might use classification systems solely for one purpose or the other. In extreme cases a public library with a small collection might just use a classification system for location of resources but might not use a complicated subject classification system. Instead all resources might just be put into a couple of wide classes (Travel, Crime, Magazines etc.). This is known as a "mark and park"
Library classification classification method, more formally called reader interest classification.[2]
Types There are many standard system of library classification in use, and many more have been proposed over the years. However in general, Classification systems can be divided into three types depending on how they are used. • Universal schemes covering all subjects. Examples include Dewey Decimal Classification, Universal Decimal Classification and Library of Congress Classification • Specific classification schemes for particular subjects or types of materials. Examples include Iconclass, British Catalogue of Music Classification, and Dickinson classification, or the NLM Classification for medicine. • National schemes specially created for certain countries. An example is the Swedish library classification system, SAB (Sveriges Allmänna Biblioteksförening). In terms of functionality, classification systems are often described as • enumerative: produce an alphabetical list of subject headings, assign numbers to each heading in alphabetical order library classification is the technical process • hierarchical: divides subjects hierarchically, from most general to most specific • faceted or analytico-synthetic: divides subjects into mutually exclusive orthogonal facets There are few completely enumerative systems or faceted systems, most systems are a blend but favouring one type or the other. The most common classification systems, LCC and DDC, are essentially enumerative, though with some hierarchical and faceted elements (more so for DDC), especially at the broadest and most general level. The first true faceted system was the Colon classification of S. R. Ranganathan.
Universal classification systems used in English-speaking world • Bliss bibliographic classification (BC) • Dewey Decimal Classification (DDC) • Library of Congress Classification (LCC) (The above systems are the most common in the English-speaking world.) • BISAC Subject Headings: The publishing industry standard for classification that is being adopted by some libraries.[3] • Harvard-Yenching Classification: An English classification system for Chinese language materials. • V-LIB 1.2 (2008 Vartavan Library Classification for over 700 fields of knowledge, currently sold under license in the UK by Rosecastle Ltd.

Newer classification systems tend to use the principle of synthesis (combining codes from different lists to represent the different attributes of a work) heavily, which is comparatively lacking in LC or DDC.
Comparing Classification Systems As a result of differences in Notation, history, use of enumeration, hierarchy, facets, classification systems can differ in the following ways • Type of Notation: Notation can be pure (consisting of only numerals for example) or mixed (consisting of letters, numerals, and other symbols). • Expressiveness: This is the degree in which the notation can express relationship between concepts or structure. • Whether they support mnemonics: For example the number 44 in DDC notation usually means it concerns some aspect of France. For example 598.0944 concerns "Birds in France". the 09 signifies country code, and 44 represents France. • Hospitality: The degree in which the system is able to accommodate new subjects • Brevity: Length of the notation to express the same concept • Speed of updates and degree of support: The best classification systems are constantly being reviewed and improved. • Consistency • Simplicity • Usability

Universal, taxonomic classification systems Taxonomy Taxonomy is the practice and science of classification. The word finds its roots in the Greek τάξις, taxis (meaning 'order' or 'arrangement') and νόμος, nomos (meaning 'law' or 'science'). Taxonomy uses taxonomic units, known as taxa (singular taxon). In addition, the word is also used as a count noun: a taxonomy, or taxonomic scheme, is a particular classification ("the taxonomy of ..."), arranged in a hierarchical structure. Typically this is organized by supertype-subtype relationships, also called generalization-specialization relationships, or less formally, parent-child relationships. In such an inheritance relationship, the subtype by definition has the same properties, behaviors, and constraints as the supertype plus one or more additional properties, behaviors, or constraints. For example: car is a subtype of vehicle, so any car is also a vehicle, but not every vehicle is a car. Therefore a type needs to satisfy more constraints to be a car than to be a vehicle. Another example: any shirt is also a piece of clothing, but not every piece of clothing is a shirt. Hence, a type must satisfy more parameters to be a shirt than to be a piece of clothing.
Applications Originally taxonomy referred only to the classifying of organisms (now sometimes known as alpha taxonomy) or a particular classification of organisms. It is also used to refer a classification of things or concepts, as well as to the principles underlying such a classification. Taxonomy is the science which deals with the study of identifying, grouping, and naming organisms according to their established natural relationship. Almost anything—animate objects, inanimate objects, places, concepts, events, properties, and relationships—may then be classified according to some taxonomic scheme. Wikipedia categories illustrate a taxonomy schema,[1] and a full taxonomy of Wikipedia categories can be extracted by automatic means.[2] Recently, it has been shown that a manually constructed taxonomy, such as that of computational lexicons like WordNet, can be used to improve and restructure the Wikipedia category taxonomy.[3] The term taxonomy is sometimes applied to relationship schemes other than parent-child hierarchies, such as network structures with other types of relationships. In that case, they might include single children with multi-parents, for example, "Car" might appear with both parents "Vehicle" and "Steel Mechanisms"; technically, this merely means that 'car' is a part of several different taxonomies.[4] A taxonomy might also be a simple organization of kinds of things into groups, or even an alphabetical list. However, the term vocabulary is more appropriate for such a list. In current usage within Knowledge Management, taxonomies are considered narrower than ontologies since ontologies apply a larger variety of relation types.[5] Mathematically, a hierarchical taxonomy is a tree structure of classifications for a given set of objects. It is also named Containment hierarchy. At the top of this structure is a single classification, the root node, that applies to all objects. Nodes below this root are more specific classifications that apply to subsets of the total set of classified objects. The progress of reasoning proceeds from the general to the more specific. In scientific taxonomies, a conflative term is always a polyseme.[6] In contrast, in a context of legal terminology, an open-ended contextual taxonomy—a taxonomy holding only with respect to a specific context. In scenarios taken from the legal domain, a formal account of the open-texture of legal terms is modeled, which suggests varying notions of the "core" and "penumbra" of the meanings of a concept. The
Taxonomy progress of reasoning proceeds from the specific to the more general.[7]
Taxonomy and mental classification Some have argued that the adult human mind naturally organizes its knowledge of the world into such systems. This view is often based on the epistemology of Immanuel Kant. Anthropologists have observed that taxonomies are generally embedded in local cultural and social systems, and serve various social functions. Perhaps the most well-known and influential study of folk taxonomies is Émile Durkheim's The Elementary Forms of Religious Life. A more recent treatment of folk taxonomies (including the results of several decades of empirical research) and the discussion of their relation to the scientific taxonomy can be found in Scott Atran's Cognitive Foundations of Natural History
Various biological taxonomies Biological classification (sometimes known as "Linnaean taxonomy") is still generally the best known form of taxonomy. It differs from the above in that it is an empirical science, with classifying only the final step of a process, and a classification only the means to communicate the end results. It also includes the prediction, discovery, description and (re)defining of taxa. It uses taxonomic ranks, including, among others, (in order) Kingdom, Phylum, Class, Order, Family, Genus, Species (various mnemonic devices have been used to help people remember the list of "Linnaean" taxonomic ranks. See Zoology mnemonic). In zoology, the nomenclature for the more important ranks (superfamily to subspecies), including the allowed number of ranks, is strictly regulated by the ICZN Code, whereas there is more latitude for names at higher ranks. Taxonomy itself is never regulated, but is always the result of research in the scientific community. How researchers arrive at their taxa varies; depending on the available data, and resources, methods vary from simple quantitative or qualitative comparisons of striking features to elaborate computer analyses of large amounts of DNA sequence data.
Phylogenetics Today, the alternative to the traditional rank-based biological classification is phylogenetic systematics, which is postulating phylogenetic trees (trees of descent), rather than focusing on what taxa to delimit. The best-known form of this is cladistics. The results of cladistic analyses are often represented as cladograms. It is held by cladists that taxa (if recognized) must always correspond to clades, united by apomorphies (derived traits) which are discovered by a cladistic analysis. Some cladists hold that clades are poorly expressed in rank-based hierarchies and support the PhyloCode, a proposed ruleswork for the formal naming of clades, based on the model of the ICZN, ICBN etc. in rank-based nomenclature.
Numerical taxonomy In numerical taxonomy, numerical phenetics or taximetrics, the taxonomy is exclusively based on cluster analysis and neighbor joining to best-fit numerical equations that characterize measurable traits of a number of organisms. It results in a measure of evolutionary "distance" between species. This method has been largely superseded by cladistic analyses today; it is liable to being misled by plesiomorphic traits.
Non-scientific taxonomies Other taxonomies, such as those analyzed by Durkheim and Lévi-Strauss, are sometimes called folk taxonomies to distinguish them from scientific taxonomies that focus on evolutionary relationships rather than similarity in habitus and habits. Though phenetics arguably places much emphasis on overall similarity, it is a quantitative analysis that attempts to reproduce evolutionary relationships of lineages and not similarities of form taxa.

Taxonomy The neologism folksonomy should not be confused with "folk taxonomy", though it is obviously a portmanteau created from the two words. "Fauxonomy" (from French faux, "false") is a pejorative neologism used to criticize folk taxonomies for their lack of agreement with scientific findings. Baraminology is a taxonomy used in creation science which in classifying form taxa resembles folk taxonomies. The phrase "enterprise taxonomy" is used in business to describe a very limited form of taxonomy used only within one organization. An example would be a certain method of classifying trees as "Type A", "Type B" and "Type C" used only by a certain lumber company for categorising log shipments.
Military taxonomy Military theorist Carl von Clausewitz stressed the significance of grasping the fundamentals of any situation in the "blink of an eye" (coup d'œil). In a military context the astute tactician can immediately grasp a range of implications and can begin to anticipate plausible and appropriate courses of action.[8] Clausewitz' conceptual "blink" represents a tentative ontology which organizes a set of concepts within a domain. The term "military taxonomy" encompasses the domains of weapons, equipment, organizations, strategies, and tactics.[9] The use of taxonomies in the military extends beyond its value as an indexing tool or record-keeping template[10] -- for example, the taxonomy-model analysis suggests a useful depiction of the spectrum of the use of military force in a political context.[11] A taxonomy of terms to describe various types of military operations is fundamentally affected by the way all elements are defined and addressed—not unlike framing. For example, in terms of a specific military operation, a taxonomic approach based on differentiation and categorization of the entities participating would produce results which were quite different from an approach based on functional objective of an operation (such as peacekeeping, disaster relief, or counter-terrorism).[12]
Economic taxonomies Taxonomies are also often used to classify economic activity, including products, companies and industries. Widely used industry taxonomies include the International Standard Industrial Classification (ISIC); national and regional taxonomies such as the United States Standard Industrial Classification (SIC), the North American Industry Classification System (NAICS), Statistical classification of economic activities in the European Community (NACE), the United Kingdom Standard Industrial Classification of Economic Activities, the Russian Economic Activities Classification System (OKVED); and proprietary taxonomies such as the Industry Classification Benchmark and Global Industry Classification Standard. The international and national taxonomies are used by official statistical agencies. The proprietary taxonomies are often used in the financial services industry to group similar investment vehicles and to construct sectorial stock market indices. Pavitt's Taxonomy classifies firms by their principal sources of innovation.
Safety taxonomies The creation of taxonomies is very important in safety science. For example there exist numerous taxonomies to classify and analyze human error and accident causes. Examples of these include the Human Factors Analysis and Classification System based on Reason's Swiss Cheese Model, the CREAM (Cognitive Reliability Error Analysis Method), the taxonomy used by CIRAS [13] (Confidential Incident Railway Analysis System) in the UK rail industry, and others.[14]

Dewey Decimal Classification The Dewey Decimal Classification (DDC, also called the Dewey Decimal System) is a proprietary system of library classification developed by Melvil Dewey in 1876; it has been greatly modified and expanded through 22 major revisions, the most recent in 2003.[1] This system organizes books on library shelves in a specific and repeatable order that makes it easy to find any book and return it to its proper place. The system is used in 200,000 libraries in at least 135 countries.[2] [3] A designation such as Dewey 16 refers to the 16th edition of the DDC.
Design The DDC attempts to organize all knowledge into ten main classes. The ten main classes are each further subdivided into ten divisions, and each division into ten sections, giving ten main classes, 100 divisions and 1000 sections. DDC's advantage in using decimals for its categories allows it to be both purely numerical and infinitely hierarchical. It also uses some aspects of a faceted classification scheme, combining elements from different parts of the structure to construct a number representing the subject content (often combining two subject elements with linking numbers and geographical and temporal elements) and form of an item rather than drawing upon a list containing each class and its meaning. Except for general works and fiction, works are classified principally by subject, with extensions for subject relationships, place, time or type of material, producing classification numbers of at least three digits but otherwise of indeterminate length with a decimal point before the fourth digit, where present (e.g. 330 for economics + .9 for geographic treatment + .04 for Europe = 330.94 European economy; 973 for United States + .05 form division for periodicals = 973.05 periodicals concerning the United States generally). Books are placed on the shelf in increasing numerical order of the decimal number, e.g. 050, 220, 330, 330.973, 331. When two books have the same classification number the second line of the call number (usually the first letter or letters of the author's last name, the title if there is no identifiable author) is placed in alphabetical order. The DDC has a number for all books, including fiction: American fiction is classified in 813. Most libraries create a separate fiction section to allow shelving in a more generalized fashion than Dewey provides for, or to avoid the space that would be taken up in the 800s, or simply to allow readers to find preferred authors by alphabetical order of surname.

Dewey Decimal Classification Some parts of the classification offer options to accommodate different kinds of libraries. An important feature of the scheme is the ability to assign multiple class numbers to a bibliographical item and only use one of them for shelving. The added numbers appear in the classified subject catalog (though this is not the usual practice in North America). For the full benefit of the scheme the relative index and the tables that form part of every edition must be understood and consulted when required. The structure of the schedules is such that subjects close to each other in a dictionary catalog are dispersed in the Dewey schedules (e.g., architecture of Chicago quite separate from geography of Chicago).
Classes listed The system is made up of seven tables and ten main classes, each of which are divided into ten secondary classes or subcategories, each of which contain ten subdivisions. The tables are: • • • • •
standard subdivision areas subdivision of individual literatures subdivisions of individual languages racial, ethnic, national groups
• languages • persons The classes are: • • • • • • • • • •
000 – Computer science, information and general works 100 – Philosophy and psychology 200 – Religion 300 – Social sciences 400 – Language 500 – Science (including mathematics) 600 – Technology and applied Science 700 – Arts and recreation 800 – Literature 900 – History, geography, and biography
Administration and publication While he lived, Melvil Dewey edited each edition himself: he was followed by other editors who had been very much influenced by him. The earlier editions were printed in the peculiar spelling that Dewey had devised: the number of volumes in each edition increased to two, then three and now four. The Online Computer Library Center of Dublin, Ohio, United States, acquired the trademark and copyrights associated with the DDC when it bought Forest Press in 1988. OCLC maintains the classification system and publishes new editions of the system. The editorial staff responsible for updates is based partly at the Library of Congress and partly at OCLC. Their work is reviewed by the Decimal Classification Editorial Policy Committee (EPC), which is a ten-member international board that meets twice each year. The four-volume unabridged edition is published approximately every seven years, the most recent edition (DDC 22) in mid 2003.[4] The web edition is updated on an ongoing basis, with changes announced each month.[5] The work of assigning a DDC number to each newly published book is performed by a division of the Library of Congress, whose recommended assignments are either accepted or rejected by the OCLC after review by an advisory board; to date all have been accepted.

Dewey Decimal Classification In September 2003, the OCLC sued the Library Hotel for trademark infringement. The settlement was that the OCLC would allow the Library Hotel to use the system in its hotel and marketing. In exchange, the Hotel would acknowledge the Center's ownership of the trademark and make a donation to a nonprofit organization promoting reading and literacy among children.
Influence DDC's numbers formed the basis of the more expressive but complex Universal Decimal Classification (UDC), which combines the basic Dewey numbers with selected punctuation marks (comma, colon, parentheses, etc.). Adaptations of DDC for specific regions outside the English-speaking world include the Korean Decimal Classification, the New Classification Scheme for Chinese Libraries and the Nippon Decimal Classification (Japanese).
Comparison with Library of Congress Classification Besides its frequent revision, DDC's main advantage over its chief American rival, the Library of Congress Classification system developed shortly afterward, is its simplicity. Thanks to the use of pure notation, a mnemonics system and a hierarchical decimal place system, it is generally easier to use. DDC and UDC are more flexible than Library of Congress Classification because of greater use of facets (via auxiliary tables) while Library of Congress Classification is almost totally enumerative. DDC's decimal system means that it is less hospitable to the addition of new subjects, as opposed to Library of Congress Classification, which has 21 classes at the top level. DDC notations can be much longer compared to other classification systems. Another disadvantage of DDC is that it was developed in the 19th century essentially by one man and was built on a top-down approach to classify all human knowledge, which makes it difficult to adapt to changing fields of knowledge. The Library of Congress Classification system was developed based mainly on the idea of literary warrant; classes were added (by individual experts in each area) only when needed for works owned by the Library of Congress. As a result, while the Library of Congress Classification system was able to incorporate changes and additions of new branches of knowledge, particularly in the fields of engineering and computer science (the greater hospitability of the Library of Congress Classification was also a factor), DDC has been criticized for being inadequate in covering those areas. It is asserted that, as a result, most major academic libraries in the US do not use the DDC because the classification of works in those areas is not specific enough, although there are other reasons that may truly be more weighty, such as the much lower expense of using a unique "pre-packaged" catalog number instead of having highly skilled staff members engaging in the time-consuming development of catalog numbers. The Library of Congress Classification system is not without problems. For example, it is highly US-centric because of the nature of the system, and it has been translated into far fewer languages than DDC and UDC.

Library of Congress Classification

Library of Congress Classification The Library of Congress Classification (LCC) is a system of library classification developed by the Library of Congress. It is used by most research and academic libraries in the U.S. and several other countries. It is not to be confused with the Library of Congress Subject Headings or Library of Congress Control Number. Most public libraries and small academic libraries continue to use the Dewey Decimal Classification (DDC). The classification was originally developed by Herbert Putnam in 1897, just before he assumed the librarianship of Congress. With advice from Charles Ammi Cutter, it was influenced by Cutter Expansive Classification, and the DDC, and was specially designed for the special purposes of the Library of Congress. The new system replaced a fixed location system developed by Thomas Jefferson. By the time of Putnam's departure from his post in 1939, all the classes except K (Law) and parts of B (Philosophy and Religion) were well developed. It has been criticized as lacking a sound theoretical basis; many of the classification decisions were driven by the particular practical needs of that library, rather than epistemological considerations. Although it divides subjects into broad categories, it is essentially enumerative in nature. It provides a guide to the books actually in the library, not a classification of the world. The National Library of Medicine classification system (NLM) uses the classification scheme's unused letters W and QS–QZ. Some libraries use NLM in conjunction with LCC, eschewing LCC's R (Medicine). Others prefer to use the LCC scheme's QP-QR schedules and include Medicine R.

Universal, faceted classification systems Faceted classification A faceted classification system allows the assignment of multiple classifications to an object, enabling the classifications to be ordered in multiple ways, rather than in a single, pre-determined, taxonomic order. A facet comprises "clearly defined, mutually exclusive, and collectively exhaustive aspects, properties or characteristics of a class or specific subject".[1] For example, a collection of books might be classified using an author facet, a subject facet, a date facet, etc. Faceted classification is used in faceted search systems that enable a user to navigate information along multiple paths corresponding to different orderings of the facets. This contrasts with traditional taxonomies in which the hierarchy of categories is fixed and unchanging. The Colon classification developed by S. R. Ranganathan is an example of faceted classification applied to the physical world, specifically for the purpose of organizing library materials. In the Colon classification system, a book is assigned a set of values from independent facets. It differs from traditional library classification schemas like the Dewey Decimal System and Library of Congress classification system, in which each document has a unique assignment in a single, hierarchically organized classification system.[2] Faceted classification systems are also distinct from folksonomies or other tagging systems that do not break out the tags into independent facets.

Bliss bibliographic classification
Bliss bibliographic classification The Bliss bibliographic classification (BC) is a library classification system that was created by Henry E. Bliss (1870–1955), published in four volumes between 1940 and 1953. Although originally devised in the United States, it was more commonly adopted by British libraries than by American ones. A second edition of the system (BC2) has been developed in Britain since 1977.
Origins of the system Bliss was born in New York in 1870 and in 1891 began work in the library of the College of the City of New York (now City College of the City University of New York). Bliss had a lifelong interest in the organization, structure and philosophy of knowledge and was very critical of the library classification systems that were available to him. He believed that because the popular Library of Congress system had been designed for a specific library (the Library of Congress) it had no use as a standard system outside that library. He also greatly disliked the Dewey Decimal system. Bliss wanted a classification system that would provide distinct rules yet still be adaptable to whatever kind of collection a library might have, as different libraries have different needs. His solution was the concept of “alternative location,” in which a particular subject could be put in more than one place, as long as the library made a specific choice and used it consistently. In 1908 Bliss reclassified 60,000 of his library’s books, and in 1910 he published an article with a rough scheme of his general ideas. But as he continued to develop his system he realized that it was going to be a much larger project than he had anticipated. The first of his four volumes appeared in 1940 (the year he retired) and the last in 1953, two years before his death. Some of the underlying policies of the BC system were: • • • •
alternative location brief, concise notation organizing knowledge according to academic expertise subjects moving gradually from topic to topic as they naturally related to one another.
Examples Bliss deliberately avoided the use of the decimal point because of his objection to Dewey's system. Instead he used capital and lower-case letters, numerals, and every typographical symbol available on his extensive and somewhat eccentric typewriter. In the revised edition (BC2), only capital letters are used, with numerals occasionally used for special purposes. Here is an extract: HJ Preventive medicine . . . HL Curative medicine HLK Primary care; general practice HLY Secondary care, aftercare

Bliss bibliographic classification
Adoption and change BC was not used by many North American libraries. The system was not without its flaws (the result of being largely a one-person project), and the layout of Bliss’s text was difficult to read. A few library schools sometimes taught the BC system to their students, but only in a minor way. The failure of the system to catch on in North America was partly because of its internal deficiencies but also because the Dewey Decimal and Library of Congress systems were already well established. The City College library continued to use Bliss’s system until 1967, when it reluctantly switched to the Library of Congress system. It had become too expensive to train new staff members to use BC, and too expensive to maintain in general. Much of the Bliss stacks remain, however, as no-one has recatalogued the books. The case was different, however, in Britain. BC proved more popular there and also spread to other English-speaking countries. Part of the reason for its success was that libraries in teachers’ colleges liked the way Bliss had organized the subject areas on teaching and education. By the mid-1950s the system was being used in at least sixty British libraries and in a hundred by the 1970s. In 1967 the Bliss Classification Association was formed. Its first publication was the Abridged Bliss Classification (ABC), intended for school libraries. In 1977 it began to publish and maintain a much-improved, revised version of Bliss’s system, the Bliss Bibliographic Classification (Second Edition) or BC2. This retains only the broad outlines of Bliss's scheme, replacing most of the detailed notation with a new scheme based on the principles of faceted classification. Fifteen of approximately 28 volumes of schedules have so far been published. The top level organisation is: • • • • • •
2/9 - Generalia, Phenomena, Knowledge, Information science & technology A/AL - Philosophy & Logic AM/AX - Mathematics, Probability, Statistics AY/B - General science, Physics C - Chemistry D - Astronomy and earth sciences

Colon classification Colon classification (CC) is a system of library classification developed by S. R. Ranganathan. It was the first ever faceted (or analytico-synthetic) classification. The first edition was published in 1933. Since then six more editions have been published. It is especially used in libraries in India. Its name "Colon classification" comes from the use of colons to separate facets in class numbers. However, many other classification schemes, some of which are completely unrelated, also use colons and other punctuation in various functions. They should not be confused with Colon classification. As an example, the subject "research in the cure of tuberculosis of lungs by x-ray conducted in India in 1950" results in a call number L,45;421:6;253:f.44'N5 The components of this call number represent Medicine,Lungs;Tuberculosis:Treatment;X-ray:Research.India'1950
Organization The Colon Classification uses 42 main classes that are combined with other letters, numbers and marks in a manner resembling the Library of Congress Classification to sort a publication.
Facets CC uses five primary categories, or facets to further specify the sorting of a publication. Collectively, they are called PMEST: , personality ; matter or property : energy . space ' time

Cutter Expansive Classification
Cutter Expansive Classification The Cutter Expansive Classification system is a library classification system devised by Charles Ammi Cutter. It uses all letters to designate the top categories of books. This is in contrast to the Dewey Decimal Classification, which uses only numbers, and the Library of Congress classification, which uses a mixture of letters and numbers. The system was the basis for the top categories of the Library of Congress classification. "No one, perhaps, can remember it all; it cannot be learned, even in part, very quickly; but those who use the library much will find that they become familiar in time unconsciously with all that they have much occasion to use." from How to Get Books by C. A. Cutter, 1882
History of the Cutter classification Charles Ammi Cutter (1837–1903), inspired by the decimal classification of his contemporary Melvil Dewey, originally developed his own classification scheme for the collections of the Boston Athenaeum, at which he served as librarian for two dozen years. He began work on it about 1880 and published the first schedules in the early 1890s. His five-volume catalogue of the Athenaeum collection is a classic in bibliographic history. The Cutter classification, although adopted by comparatively few libraries, mostly in New England, has been called one of the most logical and scholarly of American classifications. Its outline served as a basis for the Library of Congress classification, which also took over some of its features. It did not catch on as did Dewey's system because Cutter died before it was completely finished, making no provision for the kind of development necessary as the bounds of knowledge expanded and scholarly emphases changed throughout the 20th century.
Outline of the Cutter classification Like the LC classification system, texts are organized by subject. Users of Cutter, however, will find the subject headings more general than those of the LC system. • • • • • • • • •

How Cutter call numbers are constructed Most call numbers in the Cutter classification follow conventions offering clues to the book's subject. The first line represents the subject, the second the author (and perhaps title), the third and fourth dates of editions, indications of translations, and critical works on particular books or authors. All numbers in the Cutter system are (or should be) shelved as if in decimal order. Size of volumes is indicated by points (.), pluses (+), or slashes (/ or //). For some subjects a numerical geographical subdivision follows the classification letters on the first line. The number 83 stands for the United States—hence, F83 is U.S. history, G83 U.S. travel, JU83 U.S. politics, WP83 U.S. painting. Geographical numbers are often further expanded decimally to represent more specific areas, sometimes followed by a capital letter indicating a particular city. The second line usually represents the author's name by a capital letter plus one or more numbers arranged decimally. This may be followed by the first letter or letters of the title in lower-case, and/or sometimes the letters a,b,c indicating other printings of the same title. When appropriate, the second line may begin with a 'form' number—e.g., 1 stands for history and criticism of a subject, 2 for a bibliography, 5 for a dictionary, 6 for an atlas or maps, 7 for a periodical, 8 for a society or university publication, 9 for a collection of works by different authors. On the third line a capital Y indicates a work about the author or book represented by the first two lines, and a capital E (for English—other letters are used for other languages) indicates a translation into English. If both criticism and translation apply to a single title, the number expands into four lines.
Cutter Numbers One of the features adopted by other systems, including Library of Congress, is the Cutter number. It is an alphanumeric device to code text so that it can be arranged in alphabetical order using the fewest characters. It contains one or two initial letters and Arabic numbers, treated as a decimal. To construct a Cutter number, a cataloguer consults a Cutter table as required by the classification rules. Although Cutter numbers are mostly used for coding the names of authors, the system can be used for titles, subjects, geographic areas, and more.

Universal Decimal Classification The Universal Decimal Classification is a system of library classification developed by the Belgian bibliographers Paul Otlet and Henri La Fontaine at the end of the 19th century. It is based on the Dewey Decimal Classification, but uses auxiliary signs to indicate various special aspects of a subject and relationships between subjects. It thus contains a significant faceted or analytico-synthetic element, and is used especially in specialist libraries. UDC has been modified and extended through the years to cope with the increasing output in all disciplines of human knowledge, and is still under continuous review to take account of new developments. The documents classified by UDC may be in any form. They will often be literature, i.e. written documents, but may also be in other media such as films, video and sound recordings, illustrations, maps, and realia such as museum pieces. UDC classifications use Arabic numerals and are based on the decimal system. Every number is thought of as a decimal fraction with the initial decimal point omitted, which determines filing order. For ease of reading, a UDC identifier is usually punctuated after every third digit. Thus, after 61 "Medical sciences" come the subdivisions 611 to 619; under 611 "Anatomy" come its subdivisions 611.1 to 611.9; under 611.1 come all of its subdivisions before 611.2 occurs, and so on; after 619 comes 620. An advantage of this system is that it is infinitely extensible, and when new subdivisions are introduced, they need not disturb the existing allocation of numbers.

e.g. 592/599 Systematic zoology (everything from 592 to 599 inclusive)
:
colon
relation
e.g. 17:7 Relation of ethics to art
[]
square brackets
algebraic subgrouping
e.g. 311:[622+669](485) statistics of mining and metallurgy in Sweden (the auxiliary qualifies 622+669 considered as a unit)
=
equals
language
e.g. =111 in English; 59=111 Zoology, in English
The design of UDC lends itself to machine readability, and the system has been used both with early automatic mechanical sorting devices, and modern library OPACs. A core version of UDC, with 65,000 subdivisions, is now available in database format, and is called the Master Reference File (MRF). The current full version of the UDC has 220,000 subdivisions.[1]
