The first three databases listed here provide a comprehensive overview of the engineering and science literature and are top choices for starting your research. The rest are more focused topically but offer many useful features to aid discovery.
Premier index database for engineering literature. Includes Compendex (focus: civil, chemical, and mechanical engineering) and INSPEC (focus: electrical, electronics, computer engineering, and physics).
Scopus is a large abstract and citation database that includes peer-reviewed titles from international publishers, Open Access journals, conference proceedings, trade publications, and web sources. Subject coverage : Chemistry, Physics, Mathematics and Engineering ; Life and Health Sciences ; Social Sciences, Psychology and Economics ; Biological, Agricultural and Environmental Sciences.
Especially useful for locating obscure journals, name changes, and out-of-print resources. Also for determining which databases index or provide abstracts or full text for a journal.
