Database Comparisons: Specialized Subjects

Written by Stephanie Ritchie, Lauren M. Young, and Jessica Sigman. Published in Issues in Science & Technology Librarianship, Spring 2018.
Findings: "Overall, the data show that multidisciplinary databases cover agricultural subject content very well and interdisciplinary topics especially well...Notably, CAB is the one database that focuses on agriculture that covers it comprehensively. Other agricultural specific databases such as AGRICOLA or AGRIS do not provide comprehensive coverage of agricultural literature, but do offer content that is outside of the scope of large scholarly databases and of interest to agricultural researchers."

This study compares Google Scholar to Compendex and Scopus. Authors used engineering dissertations to create a data set of citations to compare Compendex and Scopus against Google Scholar. It essentially re-runs a study done 10 years ago. It concluded that Google Scholar performs better when searching for a specific resource. No topic searches were done. Simply looking for known items that had been cited in dissertations.
