This article is a description of the development of automated systems at the Mervyn H. Sterne Library at the University of Alabama in Birmingham. The authors discuss the approach taken in developing and integrating the available local and national systems into one unified management system. They examine and illustrate how the homegrown acquisitions module, the shared cataloging of OCLC and local circulation/ inventory control module under development all interface and complement each other. The integrated system is being designed to support all the local functions from a common main frame. © 1980.
