Title

Physics and astronomy databases : INSPEC and PHYS compaired

Source

Database. 14(1991) no.5, S.55-66

Year

1991

Abstract

Presents a comparison between 2 competing online databases in physics and astronomy: INSPEC and PHYS. The strengths and weaknesses of these tools are in specific subdisciplines of physics. Search strategies were formulated based on past usage and search results were analysed for speed of entry of articles, total number of hits, overlap and uniqueness of records, and document type. Concludes that, for complete coverage of many physics and astronomy topics, both databases should be searched. The superiorities of both databases over each other are listed
