Cataloging Resources

Library of Congress Cataloging Documentation

During June 2013 the Library of Congress announced that it was transitioning to online-only publication of its cataloging documentation. The printing of new editions of subject heading and classification documentation has now ceased, and all new editions and updates are now freely available on LC’s Acquisitions and Bibliographic Access (ABA) website. Information about the status and location of specific LC cataloging documentation follows below.

  • Library of Congress Subject Headings.  The final printed edition of LCSH was the 35th, published in 2013. The current edition of LCSH is made available as PDF files that may be freely downloaded. Earlier editions are available here but should not be used for cataloging.

  • Library of Congress Classification Schedules. The most current edition of each classification schedule is available as a PDF file. Earlier free editions are available here but should not be used for cataloging.

  • Subject Headings Manual (SHM). The most current version of each of the instruction sheets comprising the SHM is available as a PDF file. The files will be updated on an as-needed basis, as policies and guidelines are updated. 

  • Classification and Shelflisting Manual (CSM). PDFs of each of the instruction sheets comprising the 2013 edition of the CSM are available on the ABA website. Like the SHM, the files are updated as needed.

  • Subscription-based access to current documentation:

LCSH and LCC remain available through Classification Web, LC’s Web-based subscription service. Classification Web is a fully searchable and browsable interface for accessing the most up-to-date headings and classification numbers in LCSH, LCC, Library of Congress Genre/Form Terms for Library and Archival Materials (LCGFT), the Library of Congress Medium of Performance Thesaurus for Music (LCMPT), Children’s Subject Headings, and the LC/NACO Name Authority File. It is updated daily, and provides enhanced functionality compared to the free versions of LCSH and LCC.

The SHM and CSM continue to be available through Cataloger’s Desktop, LC’s subscription-based online documentation service. Cataloger’s Desktop provides browsing and keyword searching of over 300 cataloging and metadata resources. It is updated quarterly.

Other resources for catalogers on the Library's cataloging and acquisitions pages include Library of Congress Classification Outline, MARC standards, authority records, and more.

Library of Congress Cataloging Training Materials

The Library's Acquisitions and Bibliographic Access (ABA) website provides access to cataloging resources available through the Library of Congress. The best area of this site for cataloging training materials is the Catalogers Learning Workshop (CLW), which makes available free training resources related to the organization and classification of bibliographic information.

Other Online Cataloging Resources

Multilingual Dictionary of Cataloguing Terms and Concepts (MulDiCat)

Intended to be used for authoritative translations of IFLA cataloguing standards and related documents, MulDiCat contains definitions for many terms and concepts used by the library cataloging community. Terms and definitions are available in English and a variety of other languages.

Current Awareness

Staying abreast of the latest news and advances in library and information science can be quite difficult. The following guides link to resources librarians can use to remain current in the field.

Library Directories

Often, your local library, or your country's national library, is the best starting point for receiving assistance and locating information. Find your local library using the following directories:


Libweb currently lists over 8,000 pages from libraries in 146 countries. Search by keyword, or browse by geographic location.

The National Libraries of Europe

Information on the collections, services, addresses, and online presences of European national libraries from The European Library.

Additional resources for locating libraries can be found through the American Library Association fact sheet "Lists of Libraries."

Library Associations

Library associations are networks of professionals that gather and disseminate information to others in the field and generate public support for library and information services. If you aren't certain where to go to receive information or obtain resources needed for your library or position, you may wish to contact a local library association to seek assistance. The following website will help you locate local library associations.

Library Associations Around the World

Library Listservs

Library listservs are usually maintained by library associations and organizations. Its subscribers are typically members of that organization, or librarians with a vested interested in the listserv's goals or approved topics of discussion. Along with contacting local library associations and your local or national library, contacting appropriate library listservs is another way to receive needed information and resources in the field, and to develop contacts with other library professionals.
