The Web of Science (WoS) database has been intro‐duced recently by The Institute for Scientific Information (ISI), but no applications of it have yet been described as far as I am aware. It is compiled from 8,000 journals providing some 130,000 articles annually, covered in the combined Science (1974 onwards), Social Sciences (1972 onwards) and Arts & Humanities (1975 onwards) Citation Indexes. New journals continue to be added. At present the storage requirements for this data is about 11.5 Gbytes.
