The Ohio State University Libraries uses the Library of Congress subject headings (LCSH) to support subject searches with controlled vocabulary — in addition to the convenient keyword search. Other research libraries also use LCSH, so the subject headings can also be used in Worldcat or to search in other research library catalogs. Spending some time becoming familiar with subject headings can be helpful in conducting research. An easy way to do this is to look at the “full record” when you find a book — then click on the subject headings to find other books on the same subject (or click on the call number to find books classified in the same call number range — another kind of subject index!)

Japanese library catalogs also use subject headings. At the National Diet Library(NDL)try the advanced search . There is a guide to NDL’s subject headings.

An older edition of NDL’s subject headings is available in print:
Kokuritsu Kokkai Toshokan kenmei hyōmokuhyō

A few years ago we kept subject bibliographies in the EAS Reference collection. For specific research purposes the printed books may still be helpful —
