- 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
- A controlled set of searches have been conducted by a group of searchers, at Manchester Polytechnic Library, on a trial subset of the British National Bibliography (BNB) data base on both CD-ROM and on-line. Various measures of search effectiveness and effiency were examined in relation to the effect of the differing user interface, including recall, precision, search time, user satisfaction and other more subjective factors. Discusses the potential for further research on the evaluation of CD-ROM.

- Abstract
- Research on the use of online catalogs has challenged many assumptions about the behavior of library users. It has demonstrated that many of the patterns of behavior observed in the use of card catalogs were adaptions to the card technology; often behavioral patterns are different in an online environment. These studies have indicated that patrons prefer online catalogs and use them more, but they also show inadequacies in bibliographic practice, especially in the area of subject access.

- Abstract
- Research in user behavior on online catalogs is in its early stages, but preliminary findings suggest that users encounter many of the same problems identified in behavioral studies of other types of bibliographic retrieval systems. Much can be learned from comparing the results of user behavior studies on these two types of systems. Research on user problems with both the mechanical aspects and the conceptual aspects of system use is reviewed, with the conclusion that more similiratiy exists across types of systems in conceptual than in mechanical problems. Also discussed are potential sources of the problems, due either to individual characteristics or to system variables. A series of research questions is proposed and a number of potential interim solutions ae suggested for alleviating some of the problems encountered by users of information systems

- Abstract
- A research project at Middlesex Polytechnic is examning the problems of subject access in an OPAC. A series of user studies have been carried out which examined students' use of existing catalogue facilities, which in turn led to the experimental evaluation of various interface designs for an online catalogue. The experiments were primarily concerned with the effect of the following variables on the speed and accuracy of retrieval of specific items, the use of colour, the speed of presentation of information, the amount of information on a screen, the paging and scrolling of information, the position of a sought item within a list

- Reports results of a week long sample observation of card catalogue consultation by library users. Subsequent questioning of users about the purposes for which they consulted the catalogue revealed that the classified catalogue is not used as all and the author and title catalogue are consulted to the maximum. It is also found that 80% of the consultations of card catalogue are to locate documents, 10% is to make comprehensive searches for references on a topic and rest for miscellaneous purposes

- Abstract
- Searching behaviour in a university library is studied using a holistic approach, encompassing the use of bibliographic tools and shelf browsing. The present study is designed as the first half of a 'before and after' study to permit the evaluation of the impact of a future online catalogue on users' searching behaviour. A combined methodology was devised: searchers were encouraged to talk aloud during their search, and this information, together with some probing and real time expert interpretation, enabled the experimente to record the searching activity on a highly structured observation form. The study reveals the extent of subject searching activity, and suggests that this may have been underestimated in previous studies. The analysis of expressed topics, search formulation strategy and documents retrieved reveals the adaptive nature of the subject searching process, whereby the user adapts to the structure of the available tools. The information retrieval task in a traditional library system is tailored by the system to a single, one dimensional, sequential process. It is suggested that a major obstacle to subject searching effectiveness may lie in the lack of interaction between the different possible approaches in the searching process: the indexing language, the classification, and the titles. It is to be hoped that a future online searching environment will encourage a more truly interactive approach to subject searching.

- Abstract
- This article reports on a low-cost study of the transaction log of an online public access catalog at an academic library. The three goals of the study were to determine failure rates, to study usage patterns, and to investigate problable causes of patron problems when using the OPAC. The study found that failure rates (defined as those searches that produced zero hits) of approximately 40% are common, and that usage patterns and failure rates do not vary greatly over time or from terminal to terminal, but that the distribution of probable causes of user problems varies significantly from terminal to terminal
