- Abstract
- The implementation of our online integrated catalog ACORN at Vanderbilt University Library has been a complex and time-consuming task. The authority control component represents an important portion of the effort. The authority file consists of approximately one-half million name, subject, series, and uniform title headings, the majority of which were supplied to us by a vendor, Blackwell North America (BNA). Authority work has been integrated into our cataloging routine successfully, new headings are being added to our database daily, and extant headings are being validated online. This paper will cover a description of how Vanderbilt selected the Northwestern Online Total Integrated System (NOTIS); the ongoing editing of the authority file following the BNA processing; the interrelationship of Vanderbilt University Library's three processing units, General Technical Services (GTS), Medical Library, and Law Library apropos of the authority function; and some of the policies and procedures drawn up by the Authority Control Coordinator with the assistance of the other librarians in Monograph and Serial Services.

- Abstract
- The degree of variability in the percentage of subject searching in an online public access catalog (OPAC) among branch libraries of one university was studied. A full semester's worth of transactions was analyzed, not sampled. The time units used were hour of the day, day of the week, and week of the semester. The findings show that subject searching varies from a low of 22% to a high of 74% over the hours of a day. Variability for the days of the week ranged from 17% to 64%, and for the weeks of the semester variability ranged from 12% to 70%. Valuable management information on the utilization of the OPAC within each brach library and among all the branch libraries is provided through numerous charts and graphs.

- Abstract
- This paper reports on the successful introduction of a sophisticated online catalogue system at the library of the Scott Polar Research Institute, Cambridge, using the Muscat program package. The system provides to both end-users and library staff a choice between boolean searching on keywords and access using relevance feedback based on free text in English, mixed with UDC classification numbers. The system is implemented on an IBM 3084 computer. Significant benefits from the application of relevance feedback are reported with 10,000 records on file.

- Abstract
- LIAS, the Pennsylvania State University's (Penn State) integrated interactive online system, provides for messaging by the user to inform library staff of errors found in bibliographic records. The message is sent by use of the OOPS command, and results in a printout which is used by processing staff for online catalog maintenance. This article describes LIAS, the use of the OOPS command, the processing of the resulting OOPS reports, an assessment of the effect of its use, and some speculation on the expansion of the LIAS message system for use in catalog maintenance.
