Abstract

Considers the Internet as a means of reinvigorating education and libraries a key factor in which is distinguishing between the technological content of the Internet and its setting in a particular context, such as information literacy. In addition, a number of other important issues must be addressed including: the changing role of the Internet in the classroom, library and workplace; economic and geographic barriers to access; implications of different privatization approaches; impact of the Internet on professional school curricula; and the need for better user interfaces. Educators and librarians must ensure that the volving National Information Infrastructure (NII) reflects their needs and concerns by gaining cooperation from the public and private sectors. The result may be an education revolution in which teachers and librarians help students develop the skills necessary to succeed in an information intensive economy

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

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.
