What are the differences between DISCOVER and a library database?

DISCOVER is the Library’s one-stop searching platform. It searches across most of the library databases.

Library databases refer to the databases provided by vendors and subscribed by the Library or a few open access databases online. These databases usually have their own specific subject or resource focus. For example, in terms of resource types, there are full-text databases, bibliographic databases, numeric databases, etc. In terms of subject coverage, there are multi-disciplinary databases and subject-specific databases. Library databases may help you to search within a smaller scope so that you can find specific content.
