I notice that the new JISC Collections service has made available an "academic database assessment tool" to help libraries as they make choices about A&I and related services.
This database assessment site aims to help libraries to make informed decisions about future subscriptions to bibliographic databases.
[JISC - Compare Bibliographic and Citation Databases]
- The site provides access to detailed information and title lists for 15 major bibliographic and citation databases, and key service information for 8 major content platforms.
- In each case the information provided has been sourced directly from the relevant suppliers and is presented here as a resource to assist librarians in their purchasing decisions.
- The site provides functionality to compare databases automatically. Any combination of databases can be selected in order to generate lists of overlapping and unique titles.
has also overhauled its website since the last time I looked.
