An electronic database is an computerized collection of information, organized so that it can be expanded, manipulated, and retrieved rapidly for various uses.
Electronic databases intersect with historical research in two ways.
First, historians retrieve information from external databases. Second, historians create their own databases to help them organize their research and writing. Retrieving Data Historians most commonly use databases for bibliographical searches. It is now impossible to do thorough research without them. While the vast majority of databases available today offer bibliographical information alone, some also provide content such as texts, images, or statistics.
