A Subject Heading search must use terms as they are found in the Library of Congress Subject Headings (LCSH) list or the National Library of Medicine's Medical Subject Headings (MeSH). list. Subject Searches use "left-hand" truncation, so you only need to enter the beginning of a subject heading to browse a list of headings beginning with that term.
Select Subject from the search options and type the beginning of the subject heading. Subheadings are listed alphabetically after a main heading:
- censorship--united states--encyclopedias
Proper names can be searched as subjects to find materials about a person:
- hemingway ernest
Limits do not function in a Subject Heading search.
