Mecklersoft has been introduced to provide authors and users of library application software with an opportunity to produce and acquire software programs with a variety of applications for all library settings. Many of the programs are available in both IBM and Apple formats. This set contains all the program, format, report, label and data discussed in the book "The Essential Guide to dBase IV in Libraries". It is designed to save the user time necessary to create the database structures, report forms and program codes from scratch.
