Subject Access to Biological Information

INTRODUCTION Unless a researcher is already completely familiar with all books and articles in a particular subject (and who is?), it is necessary to do subject searches. Finding material on a particular subject is often more complicated than it seems. However, whether searchers are looking for books or articles, and whether they are looking in a paper card catalog or index, or in a computer public terminal or database, some basics stay the same. Using the right terms to look up a subject is one of the most critical steps in finding useful material, along with looking in the right places.
