Web of Science Dates of Coverage Extended

Web of Science fans will be pleased to learn that we were recently able to extend our coverage back in time significantly.

Although the database is called Web of Science, it is actually composed of three databases. Until recently, searching was limited to references from 1980 to the present.

Coverage for the three databases now is:

Science Citation Index Expanded: 1970-present
Social Science Citation Index Expanded: 1970-present
Arts & Humanities Citation Index: 1975-present **

**1975 is as far back in time as this database is available from the producer.
