Abstract

Reports results of a study to investigate judgements made by searchers of online catalogues by using transaction log analysis to associate online catalogue searchmethods with decisions so as to retrieve location information. The study used the Mainframe Interface to Libraries Online (MILO), an interface to the Illinois Library Computer Systems Office (ILCSO) online union catalogue for the 45 academic libraries belonging to ILCSO. MILO provides access to a bibliographic database and directly links to another database with circulation and location records. As the latter database only provides location and circulation status, searchers' decisions to make links to such data are seen as an indication that the records being linked represent potentially useful material. Via a transaction log analysis, the linked location records were associated wiht the access points used to retrieve them in order to analyze the value and problems of searchers' uses of specific access points. Transaction logs were analyzed for a 38-day sample of the 1994 logs. Counting of records retrieved through the use of multiple access points (making the total greater than 100%), subject fields were used to access over 30%, author fields to access over 19%, and title fields to access over 51% of all records linked to location information. Other fields were used to retrieve very small percentages of linked records

Abstract

Analyses the technical features of the 5 main search fields of the OPAC run by Bologna University's interlibrary centre (CIB), part of the National Library Service (SBN). The CIB links about 100 academic and civil library collections on the humanities, social sciences, and science subjects. With the aid of Home Page / Helpline displays, examines how OPAC search procedures are carried out by author, title, subject, ISBN, or single library. Also explains the data filtering methods used. The CIB will soon broaden its OPAC search strategies by adopting the Florence University library OPAC research structure

Abstract

Reports an examination of the results of 114 sessions on the online catalogue, at the Ellis Library, Missouri University at Columbia, to determine what types of searches were conducted and what search modes and fields (title, author) were used. Examination of tranaction logs revealed that title and author searches predominated and that the opportunity to construct Boolean searches was rarely taken advantage of. The searchers themselves reported that they were, on the whole, experienced at using the system; most searched the catalogue at least once a week. This is reflected in the relatively low instance of error and in the fact that most searches produced at least some hits. The majority of errors that were made in the process of searching were typographical

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.
