Computer/automated catalogs have been in use in secondary schools for some time and have numerous advantages. A public access catalog (PAC) allows networking with other libraries, use of the Boolean search function, and the retrieval of bibliographic citations from a variety of access points. Moreover, PAC's have recently become more user friendly. The size of the collection input into a PAC determines the hardware needs (e.g., microcomputer- or minicomputer-based). A machine-readable database using full MARC format is recommended for compatibility in the event of interface with another PAC. In addition, the following factors must be considered when preparing a PAC: (1) the attitude of the staff; (2) method of record conversion; (3) hardware acquisition; (4) the effects of the PAC on the library; and (5) appropriate file system operation. The value of an integrated library system, patron usage, and system management are other considerations which must be weighed. (KM)
