Describes a study that measured the benefits of an automated catalog and automated circulation system from the library user's point of view in terms of the value of time saved. Topics discussed include patterns of use, access time, availability of information, search behaviors, and the effectiveness of the measures used. (seven references)…

This study examined catalog records and compared the number and type of access points with number of circulations by type of user. Although little significant correlation was found between the total number of access points and total circulation, interesting trends were found in correlations by type of subject and user. (CDD)

Reports measures of the gains in search time and likelihood of success in known-item searches with the Acorn automated catalog at Vanderbilt University. User time and search success are valued in dollar terms to make the measures meaningful for system design choices. (Author/CLB)
