Cataloging for legal materials

Cataloging of law materials

Most libraries use LC (Library of Congress) or DDC ( Dewey Decimal Classification ). Some law libraries use other classifications in conjunction with these. Like a library serving a medical school may not use LCC’s R (Medicine) but rather NLM’s (National Library of Medicine) W and late Qs, legal Canadian libraries may use Canadian KF ( Common law ). Law libraries in Commonwealth countries (specially Australia and the UK) may use Moys K rather than LCC’s K (Law) or DDC’s 340, which like Canadian KF arranges Common law jurisdictions together by topic rather than first by jurisdiction.

“For the most part, the basic materials in a Law library may be found by means of publishers’ indexes and digests, Separate access to them through a catalog, therefore, is unnecessary. Many libraries find that statutes, administrative regulations and decisions, Court Reports with their auxiliary citators, digests, indexes, encyclopedias, and some periodicals can be ade- quately covered by short form cards. Topical loose-leaf services which integrate all types of basic materials fall in this group, also. However, treatises, casebooks, government documents, essays and similar col- lections, bar association reports and other miscellaneous items are not indexed, and must be controlled through cataloging with special emphasis upon subject headings.”

Assignment of subject headings in Law Libraries

The Library of Congress Tentative Headings and Cross References for a Subject Catalogue of American and English Law (1911) was the first generally used subject heading list.(1)

Because this list became out-of-date and was not revised, Columbia University published Subjed Headings in Anglo-American and International Law Used in the Dictionary Catalog of the Columbia University Law library .(2) Another list was brought out in 1956 by McLaury as List of Subject Headings for Small to Medium-Sized Law Libraries (Mainly Anglo-American).(3)

The Library of Congress Subject Headings list is the one most frequently used today because of its scope and currency.(4) Few law libraries follow it entirely, however. Modifications are made to fit the type of library and clientele. Omission of such superfluous subjects as law, legal, and law and legislation, use of direct terms, and deletion of geographical subdivisions, or their use in reversed order as main headings, are common instances of adaptation.

Moys Classification and Thesaurus

Elizabeth M. Moys (Betty) started work on her “Moys Classification for Legal Materials”as a project leading to her becoming a Fellow of the Library Association (Great Britain). After university graduation, library training, and experience as a law cataloguer in a leading London law library, Ms Moys worked in two African countries. The second of these was as Librarian of the then new University of Lagos in Nigeria, where she had the opportunity of classifying the law collection, while simultaneously building up the schedules of her scheme. She returned to England and, after many years in academic libraries, retired and become a well established legal indexer. She published a journal for legal indexers under the title: Brief Entry.

At the time of her creation of the classification, there were no LCC schedules for law. Her scheme arranges common law jurisdictions by topic (as does the Canadian adaptation of LCC’s KF), and non common law jurisdictions by jurisdiction (as does LCC). It has dual notation: Class K, as in Library of Congress and 340 as in DDC, so may be substituted for either K or 34X, as some libraries substitute NLM’s W for LCC’s R.

The demand for a legal classification in Commonwealth countries lead to its being published by Butterworths. The 4th edition, published by Bowker-Saur, is in print.

Moys differs from Canadian KF in that it uses all of K (or 34X), and so numbers are shorter, two letters and three numbers plus decimals at most.

  • K Journals and reference books
  • KA Jurisprudence
  • KB General and comparative law
  • KC International law
  • KD Religious legal systems
  • KE Ancient and medieval law
  • KF-KN Common law
  • KM Public law
  • KN Private law
  • KR Africa
  • KS Latin America
  • KT Asia and Pacific
  • KV Europe
  • KW EC

When building a number using a table, be careful to add one less than the number in the table, if the table is showing the breakdown of a series of number.

It was used in the University of British Columbia Law Library, is used at the British Columbia Court House Library, and some other libraries in western Canada. (Eastern Canada tends to use a Canadian adaptation of KF for common law.) Moys is also used in Australia, England, Nigeria, and other commonwealth countries.

Moys considers fewer countries to be common law than Canadian KF. For Moys it’s England and Wales, Ireland, Australia, Canada, New Zealand, United States, and West Indies. Canadian KF adds India, Singapore, Hong Kong, South Africa, and former British colonies of Africa.

The common law countries have their own numbers for primary materials. There is a jurisdiction and a topic index, which can also be used as a list of subject headings. As you see above, there is a sequence for the EC/EU as well as Europe as a whole and European countries.
