A number of software packages are available to help create an in-house database on a microcomputer. Because these packages vary so widely and because different programs are suited to different applications, it is useful to categorize packages by general characteristics. In-house database software can be divided into 2 broad types: 1. general purpose, which includes text retrieval, file managers, and database management systems, and 2. special purpose, which covers information storage and retrieval (IS&R) packages, integrated bibliographic systems, and library automation applications. Each type of software is appropriate in different circumstances. For example, INMAGIC and Personal Librarian, both IS&R packages selling for under $1,000, are different in strengths and weaknesses when compared together
