Abstract

An ongoing thread in information retrieval research has been the exploration of user goals (or information needs, or problems) on information retrieval systems. It has been suggested that an understanding of goals and their role in the information retrieval interaction can provide insight into appropriate retrieval strategies, relevant documents, and general system design. This article reports on empirical findings concerning goals of users searching an OPAC at a northeastern United States university. These findings were generated during a large inductive and qualitative study of users' interactions with the OPAC. It was found that respondents came to the OPAC to search for a variety of course- or degree-related projects in which they were engaged. Respondent goals were not greatly modified during the course of these interactions. A set of situational elements associated with the respondent's goal was also identified. The implications of these findings for OPAC design and the training of informational professionals are discussed

Abstract

Experiences with retrieval in OPACs suggest that there are major problems for the users of such systems, such as choosing the 'correct' subject access vocabulary, narrowing or broadening the set of items retrieved regarding the search interest. Such problems relate to two facts: (1) that in the early OPACs subject access has not been considered seriously enough and (2) that the complexity of the topic has not been really recognized. Using a typology of users' questions it is demonstrated which requirements musts be met by a successful online subject access. Improvements of subject access tools are primarily aimed at, pinpointing the interplay between the different subcomponents of any subject facility: a) the features of the indexing languages used; b) the indexing principles used; c) the design and structuring of the database; and d) the possibilities of the technical retrieval facility, the search mode, and query languages. The contribution summarizes the manifold interactions between the four subcomponents listed. Any successful retrieval will heavily depend on the design of these components considering their interactions.

Abstract

Suggests a user based approach to system design and evaluation, of computerized library systems (e.g. OPACs), which is application specific. Data was collected on 93 end user interactions with a newly implemented OPAC in a large US university library. Concludes that researchers need to explore questions relating directly to problems, faced by users and to present findings in ways which provide action oriented recommendations

Abstract

For the purposes of library and information science research, transaction lof analysis can be narrowly defined as the study of electronically recorded interactions between online information retrieval systems and the persons who search for the information found in those systems. Researchers most often use transaction log data with the intention of improving an information retrieval system, human utilization of the system, and human (and perhaps also system) understanding of how the system is used by information seekers. Transaction log analysis can provide system designers and managers with valuable information about how the system is being employed by actual users. It also can be used to study prototype systems or potential system improvements

Abstract

In the summer of 2008 all University of North Carolina libraries switched from a traditional library catalog interface supporting text-based searching (TextOnly) to a text and facet-based interface (TextFacet) to improve users' search experiences. This study seeks to understand the differences between these two interfaces and how they affect the search experience of the novice user. In this study, 40 participants were asked to search for resources using both interfaces. Their search times and accuracy were measured across three types of search tasks (known, partially known, and exploratory). After completing the searches, they were asked a series of questions about their experiences. The data were analyzed in order to identify strengths and weaknesses in both search interfaces. Thirty-six out of 40 participants preferred the TextFacet interface to the TextOnly interface. Using three dependent variables-time, accuracy, and rating-the two interfaces were compared and interactions were tested with the three task types. Search times for the TextFacet were shorter and participants preferred the TextFacet search interface over the TextOnly search interface. Performances across the three task types were different in terms of search time. The partially known and exploratory task types showed similar distributions for rating and accuracy. These distributions were distinctly different from the known task type. The results of this study may assist libraries in developing improved library catalog search interfaces that utilize facets as well as text searching.

Abstract

In an inductive, qualitative study of 30 university students (ranging from freshmen to doctoral students), it was found that their OPAC interactions were a series of situated actions. By situatedness is meant that as a user moves through an interaction, his or her actions are not completely predetermined, instead elements of the situation are utilized to determine action. The set of elements used by students in determining action is identified and described

Abstract

Controlled vocabulary and subject headings in OPAC records have proven to be useful in improving search results. The authors used a survey to gather information about librarian opinions and professional use of controlled vocabulary. Data from a range of backgrounds and expertise were examined, including academic and public libraries, and technical services as well as public services professionals. Responses overall demonstrated positive opinions of the value of controlled vocabulary, including in reference interactions as well as during bibliographic instruction sessions. Results are also examined based upon factors such as age and type of librarian.

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

Describes the availability, use and value of Z39.50, an international standard which allows a librarian accessing a database on one computer platform to search an OPAC hosted on another computer with a totally different database structure. Experiences of those working with the standard are given, and its use by the European Union IRIS project to link 6 major Irish research libraries is examined. Despite some problems encountered with different forms of author cataloguing and possible competition from the WWW, the standard is seen as possessing considerable strengths, for example in searching different catalogues and presenting the results in a standard format on screen, which justify the continuing interest of librarians

Abstract

The Bradford OPAC is an experimental prototype OPAC, with a graphical user interface, based on the manifestation concept. It was designed to study some of the problems in catalogues where there are many versions of the same work or complex multipart works. In place of the main entry based approach of one complete record for each item, the OPAC groups together into sets items that are manifestations of the same work. Users are presented with shorter lists of different intellectual works. Items in a set can be sorted, searched and displayed according to user supplied criteria

Abstract

Library OPACs have long been the gateways between users and information. They present to users the achievements of library automation, and are the most widely available automated retrieval systems and the first that many user encounter. Current trends in OPAC design are toward a user oriented, individual information service which can meet the different needs of users with a variety of background and interests. Compared with the rather inactive, short term and general information service of conventional systems, this type of system focuses on active, long term and personalized service. Proposes a framework for the design of such an OPAC and discusses some recent developments in personalized information service

Abstract

The aim of the research undertaken was to get to know the degree of implementation of discovery tools in university libraries in the Iberian Peninsula. It also allowed an initial evaluation of the facilities offered by the tools implemented. With regard to the presence of discovery tools we find a different situation in the two countries, with a higher degree of implementation in Spain. As for the behaviour of the discovery layers, the eight tools evaluated performed appropriately. Discovery tools represent a considerable advance. The combining of the library's catalogue and indexes to articles with other sources of information in a single unified interface is an unquestionable improvement. However, catalogues and databases still fulfil some purposes better than discovery tools. Libraries need to consider their clients when putting up on their websites the various tools for gaining access to contents.

Abstract

Rules regarding cataloguing, subject headings, the way information in bibliographic records is organised and the catalogue's interface, or the way the screen is set up, are barriers to the use of online catalogues by children Describes the background to and implementation of a project to create a child orientation catalogue with a graphical user interface, or one that relies on pictures instead of text, within Denver Public Library in Colorado. Now called the Kid's catalog and commercially available from the Colorado Alliance of Research Libraries Co., the catalogue's software acts as a front end to a library's regular catalogue

Abstract

Uses the results of various user studies to offer some insight into user behaviour in connection with OPAC access points and to explore conditions for subject searching, the difficulties involved and the matching of queries to subject headings. Sums up suggestions for the improvement of subject access to OPACs
