Abstract

Im Jahr 1995 entstand in interdisziplinärer Zusammenarbeit der Prototyp Bücherschatz, ein Bibliotheks-Online_katalog für Kinder. Beteiligt waren Studierende und eine Professorin der FH Hamburg, Fb Bibliothek und Information, ein Designer und 2 Informatikerinnen der Universität Hamburg. In diesem Bericht werden sowohl das Produkt Bücherschatz als auch der Prozeß seiner Entwicklung beschrieben. Ein Schwerpunkt liegt in der Auseinandersetzung mit theoretischen Modellen der Softwaretechnik - hier STEPS und Prototyping - und ihrer Anpassung an konkrete Projekterfordernisse. Weiterhin werden Fragen nach der Gestaltung kindgerechter Software, der Organisation eines großen Projektteams und nach der Art der Partizipation der Benutzer thematisiert. Das Gesamtprojekt wird in einen wissenschaftlichen Kontext der Informatik eingeordnet, und zentrale Erfahrungen und Erkenntnisse hinsichtlich interdisziplinärer und partizipativer Softwareentwicklung werden zusammengefaßt

Abstract

Reports the results of a research project, conducted by the School of Computing and Mathematics and the Library of Huddersfield Polytechnic, into the problem of matching the user interface of OPACs to the needs of users. The project brought together issues involving: Human Computer Instruction (HCI); system methods in the determinination of user requirements; and user centred design, and prototyping in a sequence of design and evaluation cycles. These cycles applied appropriate HCI styles, techniques and equipment (such as Graphical User Interface (GUI) and a mouse pointing device) and incorporated the lessons of each evaluation, to produce an OPAC user interface, ICARUS, which differs considerably in style, behaviour and characteristcs from those commonly encountered in academic and public libraries. The project concluded by evaluating ICARUS, against the BLCMP OPAC with 38 subjects in the Library of Huddersfield Polytechnic, and demonstrating a significant improvement in performance for different tasks for the ICARUS interface

Abstract

Describes a feasibility study funded by BLRDD to test a new concept in bibliographic control in OPACs based on the manifestation of the work. The research was conducted at Bradford University, leading directly from the QUALCAT project, and used bibliographic records supplied by OCLC. A new type of hierarchical bibliographic record structure was used to import sets of bibliographic records into a hierarchical relational database. This was used for an experimental Windows based OPAC. Much of the early part of the project was spent clarifying the practical and theoretical implications of the manifestations concept

Abstract

Describes work of the BOPAC2 project, funded by the British Library Research and Inoovation Centre, from Sep 1996 to Jan 1997, to investigate the issues involved in managing large and complex retrievals involving Z39.50 searches, including searches of multiple databases. The system is a WWW front end that allows simultaneously access to a number of library OPACs via Z39.50. The system is designed to make access to large and complex retrieval simpler, similar records are clustered together and retrievals may be sorted in a number of ways and by different criteria. Describes the design, development and evaluation of the system with suggestions for future work

Abstract

The destabilizing influences of the Web, widespread ownership of personal computers, and rising computer literacy have created an era of discontinuous change in research libraries a time when the cumulated assets of the past do not guarantee future success. The library catalog is such an asset. Today, a large and growing number of students and scholars routinely bypass library catalogs in favor of other discovery tools, and the catalog represents a shrinking proportion of the universe of scholarly information. The catalog is in decline, its processes and structures are unsustainable, and change needs to be swift. At the same time, books and serials are not dead, and they are not yet digital. Notwithstanding widespread expansion of digitization projects, ubiquitous e-journals, and a market that seems poised to move to e-books, the role of catalog records in discovery and retrieval of the world's library collections seems likely to continue for at least a couple of decades and probably longer. This report, commissioned by the Library of Congress (LC), offers an analysis of the current situation, options for revitalizing research library catalogs, a feasibility assessment, a vision for change, and a blueprint for action. Library decision makers are the primary audience for this report, whose aim is to elicit support, dialogue, collaboration, and movement toward solutions. Readers from the business community, particularly those that directly serve libraries, may find the report helpful for defining research and development efforts. The same is true for readers from membership organizations such as OCLC Online Computer Library Center, the Research Libraries Group, the Association for Research Libraries, the Council on Library and Information Resources, the Coalition for Networked Information, and the Digital Library Federation. Library managers and practitioners from all functional groups are likely to take an interest in the interview findings and in specific actions laid out in the blueprint.

Abstract

The ENQUIRE project forms part of a series of investigations on query expansion in the Okapi experimental text retrieval system. A configurable user interface was implemented as an evaluative tool and tested in two locations on two different databases: the library catalogue of The London Business SChool and the computing section of INSPEC. The system offered a range of possible strategies based on thesaural terms for reformulating queries. These could be initiated automatically by the system or interactively with the user. The formative phase of the evaluation established the appropriateness and usability of the interface as well as users' perceptions of the underlying functionality. The aim of the large scale field trial was to determine to what extent user would select thesaural terms suggested by the system to reformulate queries, and to evaluate the effectiveness of a new dynamic form of query expansion implemented for this project

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

This short guide describes the process for creating a CD-ROM based üublic access catalog. The authors admit that the material will be outdated by the time of publication, because product specifics change so rapidly. The report is useful, but not completely thorough. Disadvantages to using CD-ROM for public access catalog are listed, but existing methods to overcome these hindrances are not mentioned. The paper also touches on the possibility that CD-ROM-based catalogs may be more than simply an extra service, that they may become full-service catalogs in themselves
