What is classification? Classification in general The placing of subjects into categories Provides a system for organizing, categorizing knowledge Roots of current classification systems go back to Aristotles classical theory of categories Classification of books If you were organizing a collection of books, how might you arrange them?

Authors last name Title Subject Size Color Hardback vs. paperback Publisher

Public orderings Classification of books (2) Read and unread books Order of acquisition Provenance Sentimental value Private orderings

According to a classification system such as LCC or DDC Classification in libraries Use of a systematic scheme for the arrangement of books and other materials The purpose is the co-locate items on the same topic next to each on the shelf. Contrary to subject headings, classification is pretty useless in digital libraries. Some early developers & systems Francis Bacon

1605, published his outline of knowledge Jean Le Rond dAlembert 1751, published ideas on how Diderots Encyclopdie might be arranged Thomas Jefferson System based on Bacon and dAlembert Melvil Dewey Dewey Decimal Classification Charles Ammi Cutter Expansive Classification

Basic terminology Classify: To categorize, in order to arrange books on the shelves according to subject, using a classification system Classification schedules: The books (or files) that contain class numbers Notation: The system of symbols used to represent the classes in a classification system General process for classification

Analyze the subject content of the work. Summarize the primary subject focus of the work as a whole Go to the classification schedules and determine where the item should be placed within that scheme Assign the class number As appropriate for the scheme, add additional elements to the class number 14 Types of classification schemes Hierarchical Subjects are divided hierarchically, from general to specific

Enumerative All aspects of a subject are explicitly provided for in the schedules Analytico-synthetic Commonly occurring concepts (place, form, etc.) are listed once and notation is used to build or synthesize numbers Faceted Does not assign fixed numbers to subjects, but combines facets of a subject in a composite number Selected classification schemes

Most common in U.S. libraries: Dewey Decimal Classification (DDC) Library of Congress Classification (LCC) Superintendent of Documents (SuDocs) National Library of Medicine (NLM) More common outside U.S.: Universal Decimal Classification (UDC) Colon Classification (CC) Dewey Decimal Classification (DDC) Developed by Melvil Dewey in 1876 Widely used by public and school libraries in

the U.S. Used in more than 135 countries Translated into over 30 languages DDC now owned by OCLC. Access is expensive. Library of Congress Classification (LCC) Designed to arrange LCs collections Widely used in academic libraries Enumerative more is spelled out in the schedules Larger over 40 separate volumes Economical notation (shorter numbers) Considerations in choosing a classification

scheme Focus of the collection to be classified General or specialized? Maintenance of the schedules Revised to accommodate new subjects? Do revisions require reclassification? Cost Availability of catalog copy using the scheme Cost of the schedules, print and/or electronic Personnel issues Professional/paraprofessional staff, students, volunteers?

Advantages to using LCC vs. DDC? Widely available on catalog copy with complete call number Relatively unlimited expansion, not requiring wholesale revision Shorter numbers Cooperative opportunity to introduce new numbers Disadvantages of using LCC vs. DDC?

Lack of consistency among schedules Too large for an individual to fully master No single index Too complex for childrens collections Based on literary warrant from LCs collections Parts of its organization still reflect 19th/early 20th century worldview 22

Summary Classification provides a system for organizing and categorizing knowledge A number of different systems can be used for classification in libraries Classification of information resources is important: As a shelving/location device For collocation of resources To facilitate discovery of resources, whether physical or electronic 32 Purpose of LCC

Developed by the Library of Congress for organizing its own collections Adopted by other libraries, particularly academic and research libraries Initially a shelf-location device A useful retrieval tool in online systems Limited use as a tool for organizing web resources 3 Brief history (1) The Library of Congress established in 1800 when the American legislature was preparing to move from Philadelphia to the new capital city

of Washington, D.C. Section five of "An Act to Make Further Provision for the Removal and Accommodation of the Government of the United States," signed by President John Adams on April 24, 1800, provided a sum of $5,000 "for the purchase of such books as may be necessary for the use of Congress and the said city of Washington, and for fitting up a suitable apartment for containing them. Brief history (2) Early on, books were grouped by size and, within size groups, by accession number, as reflected in the first (1802) and the second

(1804) LC catalogs The first recorded change in the arrangement of the collection reflected in the Library's third catalog (1808), showing added categories for special bibliographic forms such as plans, state laws, legislative and executive reports and papers, financial reports, and gazettes. 5 Brief history (3) Burning of the US Capitol and the Library of Congresss collection in 1814 by British soldiers Purchase of Thomas Jeffersons personal

library of 6,487 books, classified by Jeffersons own system Library of Congress retaining Jeffersons classification system 6 Brief history (4) Expansion of the Library's collection from seven thousand books to nearly one million by 1890s LCs move to a new building in 1897 Contemplation of a new classification scheme for the Library Decision for its development in 1900

Provisional outline proposed in 1901 7 Brief history (5) James C. M. Hanson, Head of the Catalogue Division, and Charles Martel, the newly appointed Chief Classifier, responsible for new classification scheme Use of Cutter's Expansive Classification as a guide for the order of classes in the broad outline of the LC Classification Considerable changes made in notation Order of publication of LCC

schedules 1901 1902 E-F History: America (Western Hemisphere) Z Bibliography. Library science Additional schedules were developed throughout the twentieth century

Development of new schedules is ongoing Brief history (6) Each schedule contains an entire class, a subclass, or a group of subclasses Individual schedules of LCC developed and maintained by subject experts Conversion from print to electronic format beginning in early 1990s Conversion using the USMARC (now called MARC 21) Classification Format General characteristics of schedules Developed independently by different groups of

subject specialists Enumerative -- aspects of a subject explicitly provided by the schedules Based on literary warrant Unifying elements common to all schedules Physical format (print schedules) Internal arrangement of classes and subclasses Notation Auxiliary tables

DAW History of Central Europe KBP Islamic law KFA Law of U.S. States, Alabama to Arkansas Schedules E and F use only single letters E-F History: America E United States (General) F United States local history. Canada. Latin America Structure of LC Classification Basic arrangement is by discipline Various aspects of a subject are generally not grouped together, but are classed with the discipline

Agriculture: technical aspects in S (Agriculture) agricultural economics in HD (sub-class of Economics) Structure of LC Classification (2) Railroads: Railroad engineering in TF (sub-class of technology) Organization and management of railroads in HE (transportation and communication, a sub-class of economics) Remember: LCC separates books on the same subject by discipline

Within each subclass Subclasses further divided to specify form, place, time & subtopics Topical divisions often further subdivided by subtopics Denoted by integers 1-9999, some with decimal extensions Some subtopics may also be denoted by a Cutter number (e.g., .M84) Some subject divisions in QH Biology (General)

Interpreting the schedules Meaning is contained in the captions, not in the class numbers Class numbers merely serve to order the captions Subordination of topics is shown through indention of captions Interpreting the schedules (2) Decimal numbers do not necessarily reflect subtopics of the whole number. Decimal numbers do show that the class number was not part of the original schedule. Parenthesized numbers are not to be used; represent

class numbers that were valid in the past. Angle brackets around a number or span of numbers indicate that LC provides this number as an option but does not use it.

Book numbers Used to arrange material in a given class generally by main entry (primary access point) Usually begin with a Cutter number single capital letter, followed by Arabic numerals G73 for Grandin H84 for Hunt preceded by decimal, if this is the first Cutter

Arabic numerals represent remainder of name or title, derived from Cutter table Table is in SCM: Shelflisting G 63 Cutter Table examples After initial vowels for the second letter:b d l-m n p use number: 2 3 4 5 6 After initial letter S for the second letter:a ch e h-i m-p use number: 2 3 4 5 6

Cutter Table examples (2) After other initial consonants for the second letter: a e i o r u use number: 3 4 5 6 7 8 For expansion for the letter: use number: a-d e-h i-l m-o p-s t-v 3 4 5 6 7 9 Shelflisting

The process of determining the book number is called shelflisting Shelflist: a file of cards or bibliographic records arranged in the same order as the corresponding materials on the shelves Shelflisting: to arrange materials within a subject, normally by author; to determine the book number 14 Using the Cutter Table: first letter is a consonant Main entry: Campbell, Joseph

begin with C for 2nd letter a, use number 3: C3 expansion row : 3rd letter m-o, use 6: C36 Main entry: French political parties begin with F for 2nd letter r, use number 7: F7 expansion row: 3rd letter e-h, use 4: F74 15 Using the Cutter Table: initial vowel, initial letter S Main entry: The other eighteenth century

begin with O for 2nd letter s-t, use number 8: O8 expansion row: 3rd letter e-h, use 4: O84 Main entry: Schreiber, Daniel begin with S for 2nd letters ch, use number 3: S3 expansion row: next letter p-s, use 7: S37 16 Determining the Cutter Find the filing position in the shelflist search by class number and view main entries

in most cases, arrangement is alphabetical order by main entry Consider whether use of the Cutter table will achieve the proper position if so, use the Cutter table if not, adjust by using different numbers or by expanding with additional numbers The shelflist always takes precedence Where should a new entry file? G 100 Filing Rules has complete information General principle: File elements exactly as they

appear, word by word, then character by character File abbreviations exactly as written Treat hyphenated words as separate words Ignore initial articles (such as a, an, the) list of articles in many languages is in G 100 BUT do not ignore initial articles in personal and place names Adjusting the Cutter: expanding numbers In order to permit infinite expansion between numbers, Cutters are treated as decimals .B3
