- Abstract
- Reports results of a survey of 675 CD-ROM users at State University of New York at Albany Libraries, obtaining data from both questionnaires and actual search strategies. The primary aim was to investigate the effect of prior user training or assistance on CD-ROM search strategy. A statistically significant but weak relationship was found between prior rtraining and level of search skill. Other measures such as user status, department affiliation of major, age, sex, and number of previous CD-ROM uses were compared to search skill. Only user status and department affiliation or major were significantly correlated to search skill. Concludes that additional research is needed on the effectiveness of various types of CD-ROM training

- Abstract
- Little research has compared youngsters' use of CD-ROM and the Internet for information-seeking purposes. Nevertheless, the area has recently been addressed within a largely qualitative project more generally devoted to young people's information universes. Home access to the Internet was seen to be more limited than that to CD-ROM, although the former was consulted to tackle needs of a greater number of types. The strategies employed to exploit each form of information resource were essentially similar. No attempts were reported to check the credibility of any information retrieved from electronic sources. The Internet was, however, used more frequently beyond the informants' own homes than was CD-ROM. There was also greater employment of the Internet by adults acting an the youngsters' behalf. As Internet use for school purposes rose in accordance with age, that of CD-ROM declined. When youngsters themselves compared the two resources as information-seeking tools, CD-ROM software was criticized for its lack of detailed material and the Internet for the problems in locating what was desired. Project findings have implications in a range of areas, including the marketing of CD-ROM packages, research and development and practices within schools.

- Abstract
- This paper highlights some of the significant findings from author's PhD: "Factors affecting the end-use of electronic databases in public libraries." Public libraries have a wide range of different types of users who, unlike academic or special library users, are not necessarily information-trained (see Coles, 1998). Whereas the academic, special library user may have specific information needs that can be met by electronic sources, public library users do not necessarily have such specific information needs that can easily be identified and met. Most user surveys have tended to concentrate on the searching and retrieval aspect of information seeking behaviour, whereas this study's user survey focused more on how people perceived and related to Information and Communication Technologies (ICTs). It was not how people searched a particular electronic source, in this case CD-ROM, that was of prime interest but rather whether or not people actually used them at all and the reasons why people did or did not use electronic media. There were several reasons the study looked at CD-ROM specifically. Firstly, CD-ROM is a well established technology, most people should be familiar with CD-ROM/multimedia. Secondly, CD-ROM was, at the start of the study, the only open access electronic media widely available in public libraries. As well as examining why public library users chose to use electronic sources, the paper looks at the types of CD-ROM databases used both in the library and in general Also examined are what sort of searches users carried out. Where appropriate some of the problems inherent in studying end-users in public libraries and the difficulty in getting reliable data, are discussed. Several methods were used to collect the data. I wished to avoid limiting research to a small sample of library sites, the aim was to be as broad in scope as possible. There were two main groups of people 1 wished to look at: non-users as well as CD-ROM users

- Abstract
- The searching behaviour of 79 end-users of CD-ROM databases was studied at the UCLA campus libraries. The results indicate that users lack basic knowledge on how to search and consequently their searches are not effective despite their efforts. Users therefore need help through training but most importantly by improving the CD-ROM user interfaces and retrieval systems

- Abstract
- Die Einführung von CD-ROM Datenbanken als neue Informationstechnologie hat die Formen der Informationsgewinnung in bestimmten wissenschaftlichen Fachgebieten grundlegend geändert. Der Beitrag berichtet über Ergebnisse wissenschaftlicher Begleitforschung bei Endnutzerrecherchen in der CD-ROM-Version der Datenbank MEDLINE. Hierzu wurden drei verschiedene Erhebungen durchgeführt. Hiernach ist die überwiegende Zahl der Endnutzer (89,3%) mit dem jeweiligen Rechercheresultat zufrieden, wobei Benutzer mit geringer Rechercheerfahrung eine höhere Zufriedenheitsrate erreichen als Benutzer mit umfangreicheren Recherchekenntnissen. Die Gründe zur Nutzung von CD-ROM-Systemen resultieren voriwegend aus der klinischen Alltagsroutine oder täglichen Forschungspraxis, während vermittelte Online-Literatursuchen tendenziell häufiger im Zusammenhang mit einmaligen Ereignissen der wissenschaftlichen Aus- und Weiterbildung stehen. Die selbständige CD-ROM Literaturrecherche stellt für die befragten Ärzte und Wissenschaftler die bevorzugte Methode der Informationsgewinnung dar. Die analysierten Endnutzerrecherchen weisen allerdings Fehler und Defizite hinsichtlich einer optimalen Suchstrategie auf, die zu unbemerktn Informationsverlusten und zu Fehlbeurteilungen des wissenschaftlichen Kenntnisstandes führen

- Abstract
- W.S. Cooper's utility theory was used to evaluate end user and mediated searching of online and CD-ROM databases. The searches were conducted by 510 end users, using MEDLINE. The relevance of the references and the usefulness of the documents retrieved were examnied. The study also assessed the perceived value to end users of the information retrieved. Mediated online searching cost 3 times as much as end user CD-ROM searching, but was only about twice as effective in terms of user satisfaction; user convenience should be a high priority for the information provider and mediated CD-ROM searching may be the best compromise currently available as regards cost effectiveness and successful information retrieval for end users

- Abstract
- How postings information is used for inverted file searching was investigated by comparing searches, made by postgraduate students at the Dept. of Information Studies, of the LISA database on CD-ROM with and without postings information. Performance (the number of relevant references, precision and recall) was not significantly different but searches with postings information took more time, and more sets were viewed, than in searches without postings. Postings information was used to make decisions to narrow or broaden the search; to view or print the references. The same techniques were used to amend searches whether or not postings information was available. Users decided that a search was satisfactory on the basis of the search results, and consequently many searches done without postings were still considered satisfactory. However, searchers thought that the lack of postings information had affected 90% of their searches. Differences in search performance and searching behaviour were found in participants who were shown to have different learning styles using the Witkin's Embedded Figures test and the Lancaster Short Inventory of Approaches to Learning Test. These differences were, in part, explained by the differences in behaviour indicated by their learning styles

- Abstract
- Reports on a study conducted at Indiana University in the summer of 1993 which observed 10 advanced graduate students in language and literature studies as they conducted literature searches using databases on CD-ROM. Presents a brief review of related literature on relevance judgements, human-computer interaction (HCI) and information seeking behaviour of humanities students. The search strategies of the graduate students under study were found to be typical of humanities scholars, who create large sets and review records quickly to select relevant items. Factors influencing relevance assessments included language, source of publication, author, and length of work. Participants especially appreciated electronic access to the Modern Language Association (MLA) International Bibliography but encountered problems with the controlled vocabulary and analytic entries for books and proceedings. The study has identified problems with database content, presentation and search interfaces which should be considered by system designers

- Abstract
- Report of a study at the University of Montreal (Quebec) analysing research on the behaviour of children using information technology (online databases, CD-ROM, computerised catalogues). From a range of publications covering 6-12 year olds in the US, Canada, Europe and Oceania common features were identified: (1) children's cognitive development does not match the structured approach required for this type of information research, (2) the main abrriers were physical (e.g. using keyboard), intellectual (no capacity for abstract reasoning) and social (little access to computers); (3) in terms of natural skills, boys has greater abilities than girls. Results indicate the need to make technology more appropriate for children, and train libarrians to recognise the real capacities and limitations of children so they can teach them the basic skills

- 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
- Reports results of a survey of the online searching techniques of 50 university students, undergraduate and graduate, using the OPAC and CD-ROM databases at the Hayden Library, Arizona State University. The type of searching, use of library staff and online help screens, exposure to library user training, and length of time at the terminal for citation versus abstract products were recorded and analyzed. Results indicate that: a balance of online help products and library staff interaction is needed when providing help for users; careful attention needs to be paid to increasing the number of terminals and connections as abstracts are added to the databases being offered on the networks; and that even with exposure to more advanced searching techniques, users till rely on simple subject searching to locate required materials

- Abstract
- Reports from a study investigating the extent to which academic end users conduct multiple search sessions, over time woth OPAC or CD-ROM databases at different stages of their information seeking related to a current research project. Interviews were conducted using a questionnaire with 200 academic end users at Rutgers University Alexander Library, NJ and University of North Texas, to investigate the occurrence of multiple search sessions. Results show that at the time of the survey interview, 57% of end users had conducted multiple search sessions during their research project and 86% of end users conducted their 1st search session at the beginning stage of their information seeking process. 49% of end users had conducted between 1 and 6 search sessions and 8% more than 6 search sessions. 70% of multiple search sessionss end users had modified their search terms since their 1st search session. Discusses the implications of the findings for end user training, information retrieval systems design and further research

- Abstract
- Observes that whether in academic, special, or public libraries or on commercial online systems, CD-ROM, the online catalogue, or the Internet, certain end user errors crop up repeatedly. Details the main errors, which include input errors, errors arising from confusion in the face of different interfaces and screen designs, Boolean logic errors, term errors, conceptual errors, and errors due to the fact that users do not read instructions. Concludes that systems must solve the trivial errors automatically, but user instruction librarians must help solve the more complex problems

- Abstract
- An 2 biowissenschaftlichen Einrichtungen der Grundlagenforschung, dem Max-Delbrück-Centrum für Molekulare Medizin, Berlin-Buch und dem Leibniz-Institut für Neurobiologie, Magdeburg, wurden 1997 bzw. 1998 Nutzerbefragungen durchgeführt. Obwohl die untersuchten Gruppen beträchtliche Altersunterschiede aufwiesen, ergeben sich einheitliche Trends: für etwa 2/3 der Wissenschaftler ist gegenwärtig die Nutzung von Printmedien und elektronischen Informationsofferten gleichwertig, während etwa 15% der Befragten letzteren den Vorzug geben.

- Abstract
- Reports results of an investigation, undertaken at Sheffield University, Departmant of Information Studies, UK into the effects of postings information (the display on the screen of the number of references in the retrieved sets) on searching behaviour. Linked online searches were conducted, on the LISA database on CD-ROM, with and without postings information. Performance in terms of the number of relevant references, precision and recall was not significantly different whether postings information was available or not; but searches with postings information took more time and more sets were viewed than in searches without postings. Searchers thought that the lack of postings information had affected 90% of their searches. Proposes that training should place greater emphasis on the value of postings information at different stages of the search and should optimize the searching behaviour of those with different searching styles

- Abstract
- Reviews work of the Getty Art History Information Program (AHIP), recently renamed the Getty Information Institute, where humanities scholars were trained in DIALOG online searching and then allowed 24 hour unlimited access to DIALOG searching and DIALOG databases and where complete transaction logs were taken to yield the data upon which the Getty Online Searching Project was based. Summarizes results of the study of this subsidized access which was reported in a series of papers by M.J. Bates, who found that searching patterns of humanities researchers differed substantially from previous studies in the sciences and social sciences disciplines. Presents a model of the relative merits and opportunities associated with the various contractual arrangements and incentive strategies employed by AHIP with vendors such as DIALOG, consortia such as the Research Libraries Group, and a CD-ROM publication programme, compared to print publications and the experimental offer of access to some of the AHIP databases over the WWW. The arguments are illustrated by means of 2 case studies, involving: changes in pricing of the Avery Index to Architectural Periodicals; and the Getty Online Searching Project
