Title

Tables of contents and book indexes : how well do they match readers' descriptions of books?

Abstract

The author collected information about tables of content and index terms in 125 books borrowed by patrons in a medium-sized academic library. To learn how useful the term would be as subject terms in a library catalog, he determined which of these terms were the same as the words used by the patrons to describe the books. For 72,4% of the books assigned LCSH, the patron's term matched the LCheading. The patron's term matched the table of contents term for (1,3% of the books with tables of contents. If the catalog had included terms from the tables of contents and the indexes in addition to the LCSH, the success rate would have been 97,3%. One problem in using terms from books in a library catalog is that many books lack indexes and/or tables of context
