Using the Library of Congress Classification H Schedule

This webinar will cover some of the more complex aspects of using the "H" schedule to create classification numbers, including use of various kinds of tables, special topics, and subdivisions for industries and trades.

Originally presented on Wednesday, May 2, 2012.

Learning Outcomes

At the end of the presentation, attendees will be able to:

  • shelflist according to the Regions and Countries Table
  • use internal tables to subdivide by local geography, or firm name
  • apply external tables to subdivide by geography, form, time period, or subject

Who Should Attend

The presentation is geared toward catalogers with some experience using the "H" classification, and thus will not cover basic skills.
