EBSCO Host is the provider of more than 60 library databases. One advantage of purchasing multiple databases from a single vendor is the ability to search multiple databases at once. For example, America: History & Life, Historical Abstracts and Humanities International Complete, all databases provided by EBSCO, can be searched as a group, or SocINDEX and Social Work Abstracts can be searched together. Just click the Choose Databases link at the top of any EBSCO database search page to select a group of databases to search.
