This digest provides a brief explanation of what a database is; explains how a database can be used; identifies important factors that should be considered when choosing database management system software; and provides citations to sources for finding reviews and evaluations of database management software. The digest is concerned primarily with databases and software for handling management-type information. It is noted that databases that are bibliographic in nature are accessed primarily through subject headings and keywords, and require a different approach and generally a different type of software called information retrieval software. This digest contains sections on how databases are organized and used, and software selection considerations. A list of print and online resources that may be helpful in developing a list of possible software programs to meet specific needs is included. (THC)
