A library database is a searchable collection of information. The library subscribes to many databases, which are provided by various companies such as ProQuest, EBSCO, etc. Each database contains specific types of information--this is often referred to as a database's coverage. A database's coverage usually limits by the type of material (e.g., articles, video, artwork), the field of study, time periods, or language. Coverage notes can be found below the database's title on the Databases page.
