Ei Compendex

Ei Compendex is an engineering bibliographic database published by Elsevier. It indexes scientific literature pertaining to engineering materials. Beginning in 1884, it was compiled by hand under the original title of Engineering Index. The name "Compendex" stands for COMPuterized ENgineering inDEX.[1] As a result of computerization in 1967, the first electronic Engineering Index bulletin was sent to 500 subscribers.[2] Elsevier purchased the parent company Engineering Information in 1998.[2]
