an engineering information for two databases, Inspec and Compendex.
Compendex: Indexes to journals, conferences, technical reports of engineering and applied science; from 1969 to present; updated weekly INSPEC (via Engineering Village 2)
Abstracts of scientific literature in electrical engineering, electronics, physics, control engineering, information technology, communications, computers, computing, and manufacturing and production engineering; from 1969 to present; updated weekly
Ei covers literature that makes a definite contribution to knowledge in the subject areas of engineering and applied science. About half the citations (from 2600 journals and conferences) include abstracts and indexing in the records. Online coverage is from 1884 to the present, and files are updated weekly. The highest percentages of journal literature are in the fields of chemical and process engineering (15%), computers and data processing (12%), applied physics (11%), and electronics and communication (12%) In addition Compendex includes civil engineering (6%) and mechanical engineering (6%). USC's subscription to the Engineering Village 2 (EV2) platform includes access to the Compendex and Inspec databases.
