Databases with ebooks
Temple pays for access to databases with ebooks from specific publishers. A number of them are specialized. The descriptions of the databases on this list should give you an idea of the content you are likely to find in each. These are the sources in which Library Search finds ebooks.
You can also use the search box by DATABASES labeled "Search for Databases" with a general subject term to narrow it down, for example: "Biology AND ebooks"
