Abstract

This study is based on the data from a survey of catalog use at three university libraries and one public library. Both "known-item" searches and "subject" searches were analyzed. The characteristics of the user population were examined and methodological problems of the survey were discussed. A relation was found between the academic rank of the catalog users and type of search that they carry out. Some of the factors influencing the success or failure of the search were analyzed, and the meaning of "success" for the two types of search was discussed. The study investigated trends in search strategies as well as degree of perseverance of catalog searchers. Implications for the design of modern information retrieval systems were pointed out.
