Search Diamond to find primary sources in books and other printed works. Begin by taking just a few minutes to understand Library of Congress Subject Headings, or LCSH for short. Subject headings are "tags" applied by professional librarians to records in library catalogs. They are similar to but more precise and systematically applied than the tags you are probably already familiar with from blogs and social media sites.
Such tags offer researchers accurate descriptions of books and other library resources. Critically, subject headings provide information about the type of work described: primary source, biography, bibliography, etc. Remember that the term Sources is used as a subheading in LCSH to identify primary-source material. Other primary-source subheadings include Personal Narratives, Correspondence, and Diaries.
