Abstract

Reports results of 2 separate but related projects to study the influence of spelling errors (misspellings), made by searchers, on the subject searching of online catalogues and to suggest ways of improving error detection systems to handle the errors that they detect. This involved the categorization of user queries for subjects that were extracted from the online catalogue transaction logs of 4 USA university libraries. The research questions considered: the prevalence of misspellings in user queries for subjects; and how users respond to online catalogues that detect possible spelling errors in their subject queries. Less than 6% of user queries that match the catalogue's controlled and free text terms were found to contain spelling errors. While the majority of users corrected misspelled query words, a sizable proportion made an action that was even more detrimental than the original misspelling. Concludes with 3 recommended improvements: online catalogues should be equipped with search trees to place the burden of selecting a subject the system instead of the user; systems should be equipped with automatic spelling checking routines that inform users of possibly misspelled words; and online catalogues should be enhanced with tools and techniques to distinguish between queries that fail due to misspellings and correction failures. Cautions that spelling is not a serious problem but can seriously hinder the most routine subject search

Abstract

Examines the future of the cataloguer in an increasingly electronic environment arguing that this future will depend on adopting a more holistic approach that broadens the concept from cataloguing to the organization of information. If the goal of libraries is to provide access to information it is the organizational tools created by cataloguers that help meet this goal. Cataloguers must be aware of the potential uses of information and how it may be exploited and administrators must capitalize on cataloguers' expertise when information systems based on their work are developed

Abstract

Places present day UK culture and society in a postmodern context and considers their impact and cataloguing, concentrating specifically on the concepts of globalization and the death of tradition. Discusses how libraries can continue to provide high quality, structured access to their collections and the need for strategic management of this process. Emphasizes the importance of defining what the library want to achieve, setting objectives, and maintaining the capacity for flexible response to changing conditions, using as a case study the development and implementation of the British Library cataloguing strategy

Abstract

Observes how traditional cataloguing differs from the use of metadata to describe the materials in a digital library. Introduces the 3 categories of metadata that have been identified: descriptive (also called intellectual), structural, and administrative. Notes that MARC only deals well with intellectual metadata. Discusses some emerging standards that may be to digital libraries what MARC was to print libraries, the best of these being the Dublin Core

Abstract

Explains the background to resource sharing as it has developed in Canada. Descrbes the vCuc (virtual Canadian union catalogue pilot project) which is being completed under the umbrella of the national resource sharing strategy. Lists the goals of the project, the main one being to demonstrate the feasibility of using Z39.50 standards to emulate a centralized union catalogue, and the challenge and issues to project gave rise to. Discusses the pros and cons of Z39.50 and the aereas where it needs development and, most importantly, integration into vendor systems

Abstract

Cataloguing has always depended on choices made by non cataloguers and it has been driven by technology. Technological innovations expand the range of materials requiring bibliographic control and also improve the quality of that control. In the near future, economic factors will constrain opportunities to continue improving quality. Technological factors will continue to broaden demands on cataloguers. Inability to continue expanding the revenue streams of supporting institutions will limit cataloguer's efforts while rapid growth of information bearing technology, particularly on networks, will inflate demands for cataloguing. Librarians must develop expanded skills with automation networks and modern software systems if they are to maintain control

Abstract

Contends that library catalogues need to be seen as merely part of the information seeker's world and proposes the concept of a learning catalogue for library clients which will capture ways in which clients use data thus providing ideas for the further development of the system. Proposes a client centred system which is separated to maintain the bibliographic database from the mode of presentation of that data to the client. The designer of retrieval systems, by accepting that each client brings a unique view of the world's knowledge base to the information seeking activity, needs to acknowledge that this view of the world must be handled uniquely. By overlaying the idea of a learning component, it is possible to see how future queries might be handled more efficiently and the system can grow with client's developing needs

Abstract

The foundations of the card catalogue, catalogue use studies what can be conjectured about user needs suggest that future catalogues, as they are made possible throught the manipulations of computerized bibliographic records, ought not to take a single format. The concept of the main entry will no longer be valid at this point and multiple access points will be possible. Machine based systems will allow librarians to construct a series of catalogues to meet user needs. Proposes that there might be 3 catalogue levels of varying form and size to meet the needs of different levels of use and types of users: librarian's catalogue with full details; general user's catalogue, a location tool; and individual user's catalogue, full records in particular fields. Users could add their own material to their own catalogues and SDI via a message device would be possible

Abstract

The work begins by reviewing publications on the use of optical-disc technology in cataloging departments. This section includes descriptive information on specific products and comparative considerations on the value of the CD genre. Most commentary to date seems to find cost advantages to the optical format for smaller libraries but fewer attractions for larger institutions who would lose online immediacy. An outline of the design and results of the OCLC test follows along with various tables showing the class makeup of the overall sample, the hit-rate for the two vendors, and other data. Most of the sample consisted of English-language titles that would support the general academic mission of a variety of disciplines. Well over 90% of the titles searched had MARC records on discs within two issues or three months. Although concluding that departments acquiring over 5000 titles per year may find online utilities more effective, the article still urges a careful analysis of laser cataloging products with a variety of acquisition samples and for a variety of libraries.

Abstract

Many small libraries do not have the resources to build a holdings database but the availability of affordable scanners and improved OCR software has made possible a new approach for creating online databases. Describes the work undertaken at the Otto Hahn Library of the Max Planck Institute for Biophysical Chemistry, Germany, to create a database consisting of the titles, bibliographic descriptions and contents tables of books acquired by the library. The book information and table of contents pages are scanned and converted to text using OCR software. A computer program is used to extract as much information as possible, in particular from the CIP data with corrections and missing information being supplied manually. Finally, the information, which consists of: title; author; ISBN; publication year; call number; series; language; and other relevant information for books, as well as the entire table of contents, is stored and added to an Ovid database using the Ovid Local Loader software. Pays particular attention to the algorithm used to extract specific information from the CIP data. 2 OCR software packeges have been tested: OmniPage Pro 7.0 and FineReader 3.0. Experience has shown that FineReader is better at character recognition and retains the formatting better but OmniPage Pro is easier to train to recognize special characters
