- Abstract
- The library of the Cité des Sciences et de l'industrie attracts 4.000 visitors daily of whom 25% consult the GEAC system OPAC. Describes a 1992 survey consisting of online questions followed by an interview. The questionnaires were adapted from ones used in the UK and utilised OLIVE (Online Interactive Validation and Evaluation). While difficulties arose from users' inconsistency in their replies and failures to answer questions, it has become clear that subject access is unsatisfactory, sometimes because of mistyping by the searcher but also because of the vocabulary problems and lack of guidance in search strategies

- Abstract
- A survey of catalogue use in 1993 at Utrecht University in the Netherlands showed considerable dissatisfaction with the online catalogue's subject search facilities. Of those who used subject searching 64% preferred subject headings against only 2% who chose classification schedules. Library users make little use of the existing facilities for assistance and leaflets which are available in the library. It has, therefore, been decided to provide a programme of instruction in library use and to move towards a unified system of subject access to the library's catalogue

- Abstract
- An exploratory research study on OPACs was done within the framework of the French PARINFO program by four different teams: ENSSIB-CERSI, City Univ. of London, Médiathèque of the Cité des Sciences et de l'industrie and a firm GSI-ERLI. During the month of June 1992, 650 individual searches on four terminals were collected. The sessions were automatically recorded, accompanied by two online questionnaires, a pre-search and a post-search questionnaire. Some questions were asked orally by an interviewer and the answers noted. The article analyses the researches perceived by user as difficult or impossible. Some examples of the difficulties are given

- Abstract
- Briefly reviews research on users and online catalogues, focusing on the different data gathering methodologies. OLIVE, an enhanced facility for logging transactions and introducing online questionnaires as a front end to a personal computer, was used to examine user intentions, search formulations and success ratings on several commercial systems. Describes a third generation system, OKAPI, which addresses some of the issues raised by the user feedback

- Abstract
- Reports on 4 experiments conducted at Sheffield University, Department of Information Studies, UK, into cognitive models which illuminate how people learn using electronic media. The experiments dealt with: learning strategies in an unconstrained electronic environment, in a hypertext environment, and in database searching, and matching and mismatching learning styles. Discusses the positive or negative implications for the design of electronic learning materials suggested by these experiments

- Abstract
- Presents some results from research into the uses and usefulness of electronic bibliographic databases in academic contexts, carried out as part of a British Library funded research project. Ethnographic and focus group data was gathered initially in 3 departments (natural science, social science and humanities) at the University of Kent at Canterbury covering all academic staff, researchers and postgraduates. This was then expanded to postgraduates and staff in the same 3 disciplines at other universities. 5 themes from this research are outlined: who uses the system, who does not, and where are these activities and inactivities happening; where does formal training occur; and where does learning occur. The problems of interface between computer systems and users often mirrored that between library enquiry staff and users where users did not know to frame questions and the advice given was not in a form understood by the users

- Abstract
- Summarizes findings of an international study on information-seeking habits and preferences: With extensive input from hundreds of librarians and OCLC staff, the OCLC Market Research team developed a project and commissioned Harris Interactive Inc. to survey a representative sample of information consumers. In June of 2005, we collected over 3,300 responses from information consumers in Australia, Canada, India, Singapore, the United Kingdom and the United States. The Perceptions report provides the findings and responses from the online survey in an effort to learn more about: * Library use * Awareness and use of library electronic resources * Free vs. for-fee information * The "Library" brand The findings indicate that information consumers view libraries as places to borrow print books, but they are unaware of the rich electronic content they can access through libraries. Even though information consumers make limited use of these resources, they continue to trust libraries as reliable sources of information.

- 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
- Patron queries at a four-year comprehensive college's online public access catalog were examined via transaction logs from March 2007. Three representative days were isolated for a more detailed examination of search characteristics. The results show that library users employed an average of one to three terms in a search, did not use Boolean operators, and made use of limits one-tenth of the time. Failed queries remained problematic, as a full one-third of searches resulted in zero hits. Implications and recommendations for improvements in the online public access catalog are discussed.

- Reports on a dramatic shift from subject to periodical title searching at Colorado University Libraries. States possible reasons for the change, examines problems encountered by users with searching the periodical title index and suggests how this change in online catalogue searching may affect future catalogue design and bibliographic instruction

- Abstract
- User persistence in displaying postings is a significant human factor in the design of computer driven information systems, including online catalogs. Expert opinion and a study of users of a first generation online catalogue have suggested that users normally display no more than 30 to 35 postings. A follow up study on a second generation system with a larger database found that a greater proportion of users reported overload, but 100 postings (rather than 15) were considered 'too many'. Partially persistent users typically displayed 28 postings, but overloaded uses did not outnumber totally persistent users until postings retrieved exceeded 200. The findings suggest that, given sufficient resources, designers should still consider 30 to 35 postings typical persistence, but also justify treating 100 or 200 postings as a common threshold of overload

- Abstract
- This article reprots the findings of an experiment employing a simulated scholarly use of an OPAC to determine the frequency of one-screen displays when a scholar searches for a known-item with so-called 'keywords' in an implied boolean system. The experiment revealed that a 'keyword' search formula comprising surname plus first and last title words produced a single screen 92.8% of the time, thereby reducing the failure of traditional title searching to produce single screens by nearly one half; such a formula also enables a scholar to search successfully with abbreviated, unsearchable bibliographic citations. Additional research should be carried out, for if it is further demonstrated that replacing traditional bibliographic catalog entries with transcribed title pages provides an improved known-item OPAC, users would benefit and libraries would enjoy huge savings

- Abstract
- Reports on a study at an elementary school in Washington, DC examining pupils' use of an OPAC. Presents this within the overall instructional environment of the school in order to open a window on the broader interaction of children, technology, curriculum, instruction and learning. Explains the methodology used in the study, the findings of the study, and notes a number of conclusions. Focuses in particular on the patterns of success and failure of children's use of the OPAC, their search strategies and the nature of their interaction with the OPAC
