This "Annual Report," July 1969 to June 1970, is the fourth progress report of the Institute of Library Research. The activities of the Institute encompassed the completion of several projects and the initiation of other projects during this period. One recorded milestone of singular importance was the establishment in June 1970 of the Library System Development Project. The goal of this intramurally funded activity is to design, develop, and test computer based modules and subsystems for implementation on the campuses of the University of California. Each project can be identified as helping to resolve needs and issues in one or more of the following six areas of concern: (1) values in library and information service, (2) library and information systems, (3) methodology research, (4) information services development, (5) social and professional issues, and (6) mechanization of library processes.
