The first stage of a study on the potential for collaborative development in library automation involved a study of more than 150 recent reports and papers, and visits to library sites in the United Kingdom, Scandinavia, West Germany, and the United States. Systems models were advanced to provide a basis for testing development proposals. Further study was recommended on the following topics: (1) minicomputer based library package systems; (2) the problems of handling non-MARC materials in computerized systems; and (3) the potential for a library oriented computer language. It was concluded that cooperation in library automation is both practical and desirable. (Author/EMH)
