An indexing system to 1850 documents on library automation, systems studies in libraries, and indexing systems was developed for use in instruction and research. The indexing system consists of an on-line searched coordinate index, a printed coordinate index, a subject authority list, an abstract bulletin containing the 1850 documents in the index, computer-assisted instruction for index preparation, and searching, and a programmed text for teaching index preparation. The system has been used for instruction of graduate library school students in index preparation, searching, and evaluation. (Author)
