- Abstract
- More and more libraries are providing access to Web resources through OCLC's (Online Computer Resource Center) Cooperative Online Resource Catalog (CORC) and, by extension, OCLC's WorldCat database. The ability to use a database to its maximum potential depends upon understanding what a database contains and the guidelines for its construction. This study examines the characteristics of Web resources in CORC in terms of their subject matter, the source of the content, publication patterns, and the units of information chosen for representation in the database. The majority of the 414 resources in the sample belonged to the social sciences. Academic libraries and government agencies contributed more than 90% of the records for resources in the sample. Using the Anglo-American Cataloguing Rules, 2d edition (AACR2) definitions for publication patterns that are part of the upcoming 2002 amendments reveals that nearly half of the sample fell into the category of integrating resources. Identifying units of representation of the resources described was more difficult. Existing definitions for Web units in development are not adequate to describe all of the resources in the sample. In addition, there is wide variability in the units of representation chosen for inclusion by the libraries contributing records, resulting in little predictability in what units of information might be found in the database.

- Abstract
- Identifies and characterizes the knowledge used by experienced librarians while searching for subject information in online catalogues. 10 experienced librarians performed the same set of 6 subject searches in an online catalogue. Investigates the knowledge used to solve retrieval problems. This knowledge presents expertise in the use of the catalogue. Data were collected through the use of think aloud protocols, transaction logs and structured interviews. Knowledge was defined as knowledge objects (factual knowledge), knowledge of events (experimental knowlegde), knowledge of performance (process knowledge), and metaknowledge. Metaknowledge is the sense of whole derived from the integration of factual, process, and experimental knowledge about the search and the conditions under which it is performed. Focuses on metaknowledge. For evidence of metaknowledge the data were examined for explanations that participants gave for their actions and observations, and for ways that participants evaluated their own progress during the process of searching. Reasons and explanations given by searchers were related to all phases of the library information retrieval process from the user's receipt of material to policies for collection development, and not just events directly related to the performance of a particular search task

- Abstract
- Provides a brief summary of an OCLC funded project 'Identifying barriers to effective subject access in library catalogues'. The study investigated the probability that a skilled catalogue user would retrieve 'the best' materials on some subject, and if they were unable to do so, to determine how this could be improved. The transformation of the card catalogue onto an online database has not improved subject access. Offers a view of research in the context of the education and research roles of the library and information science educator. Discusses the university research environment, teaching students research skills and OCLC

- Abstract
- 51 subject searches were performed in an online catalog containing about 4,5 million records. Their success was judges in terms of lists of items, known to be relevant to the various topics, compiled by subject specialists (faculty members or authors of articles in specialized encyclopedias). Many of the items known to be relevant were not retrieved, even in very broad searches that sometimes retrieved several hundred records, and very little could be done to make them retrievable within the constraints of present cataloging practice. Librarians should recognize that library catalogs, as now implemented, offer only the most primitive of subject access and should seek to develop different types of subject access tools. - Vgl auch Letter (B.H. Weinberg) in: LTRS 36(1992) S.123-124.
