Coverage Dates: 1975 - present

Covers research literature from all areas of mathematics, both theoretical and applied, and also covers related areas such as computer science, engineering, physics and statistics. This database corresponds to the printed indexes, Mathematical Reviews and Current Mathematical Publications.
Abstracts and index: 1940-present

The web version of Science Citation Index (SCI) and Social Science Citation Index (SSCI). The Web of Science accesses a multidisciplinary database of bibliographic information gathered from thousands of scholarly journals. The databases are indexed so you can search for specific articles by subject, author, journal, and/or author address. Because the information stored about each article includes the article's cited reference list (often called its bibliography), you can also search the databases for articles that cite a known author or work.
