Abstract

Information research using keywords is largely ignored by readers but in medium sized libraries such as that of the City of Science and Industry (Paris), with a multimedia collection of some 200.000 documents, it is the most effective tool. The reader, however, needs guidance in using this technique, and in refining searches to reduce noise. Examples are given demonstrating how keyword searches can identify non-indexed material, documents in other languages, and collective authors
