This report discusses an ex post facto study that was done to examine the effect that the implementation of automated systems has had on libraries and support staff, labor costs, and productivity in the cataloging divisions of the library of the University of British Columbia. A comparison was made between two years: 1973, a pre-automated period when a comprehensive set of job descriptions for library positions had been written; and 1986, when an in-house automated cataloging system was in place. A discussion of certain assumptions and limitations that apply to the study is followed by an extensive review of the related literature. The experience of the library's cataloging divisions with automation is then reviewed in an attempt to answer seven research questions. Data required for the study were obtained from library and personnel department records. Analyses of these data indicated that automation in this library had the following effects: (1) an increase in the number of librarians; (2) a decrease in the number of support staff; (3) an increase in the ratio of librarians to support staff; (4) changes in duties and responsibilities of librarians and support staff; (5) apparently reduced labor costs; and (6) increased productivity. Appendixes contain organization diagrams for 1973 and 1986 as well as 12 tables displaying the results of the data analyses. (51 references) (CGD)
