Q. What types of materials are cataloged at the Library of Congress (LC)?


The Library of Congress completes bibliographic cataloging for materials that are selected for addition to the collections. The cataloging provides for the identification, description, and access to these materials, which include items in hundreds of languages and virtually every format – either analog or digital. The range of formats includes books, journals, government documents, maps, globes, atlases, microforms, e-resources, sound and video recordings, prints, drawings, photographs, films, manuscripts, braille books and music, and other formats. While virtually all subject areas are represented in the collections, the Library does not attempt to collect comprehensively in the areas of clinical medicine and technical agriculture. These subjects are collected by the National Library of Medicine and the National Agricultural Library, respectively. (Works deposited for copyright registration are also cataloged following copyright cataloging procedures.)
