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

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

At the end of 2005, impending digitization efforts and several developments related to the creation of access and discovery tools for informational and cultural objects resulted in a series of responses that continue to ripple throughout the library, museum and archive communities. These developments have broad implications for all three communities because of the goals shared by each in the creation of description, control and enhanced access to informational and cultural objects. This position paper will consider new implementations of faceted navigation and browsing features in online catalogs. It is also a response to challenges to develop interwoven approaches to the study of information seeking and the design and implementation of search and discovery systems. Urgently needed during this time of experimentation, development and implementation is a framework for system evaluation and critical analysis of needed and missing features that is grounded in traditional principles, borne out by practice. Such a framework could extend feature analysis protocols established during the early years of online catalog development.

Abstract

Purpose - The purpose of this paper is to provide an overview of the OPAC integration in the University of Michigan's local implementation of materials digitized in the partnership with Google. Design/methodology/approach - The paper provides a discussion of different strategies used in integrating metadata with digital resources and presenting the digital objects to the user in the OPAC. Findings - The paper finds that methods that had served in smaller digitization projects require more automation and error reduction processes in an undertaking of this scale. Increased integration with the OPAC is one approach. Originality/value - Michigan is the first of the Google partners to mount their materials themselves and others involved in mass digitization may be interested in the experience.

Abstract

The article is a researcher's eye view of the value of the library catalog not only as a database to be searched for surrogates of objects of study, but as a corpus of text that can be analyzed in its own right, or incorporated within the researcher's own research database. Barriers are identified in the ways in which catalog data can be output and the technical skills researchers currently need to download, ingest, and manipulate data. Research tools and datasets created by, or in collaboration with, the library community are identified.
