In this article, problems users are having searching for known works in current online public access catalogs (OPACs) are summarized. A better understanding of AACR2R/MARC 21 authority, bibliographic, and holdings records would allow us to implement the approaches outlined in the IFLA Functional Requirements for Bibliographic Records to enhance, or â FRBRize,â our current OPACs using existing records. The presence of work and expression identifiers in bibliographic and authority records is analyzed. Recommendations are made concerning better indexing and display of works and expressions/manifestations. Questions are raised about the appropriateness for the creation of true catalogs of clientserver technology that deliver records over the Internet.

This is a preprint of an article published in the Journal of the American Society for Information Science and Technology, 53, 145-161. This study examines the problem of the judgment of information quality and cognitive authority by observing people's searching behavior in the Web. Its purpose is to understand the various factors that influence peopleâ s judgment of quality and authority in the Web, and the effects of those judgments on selection behaviors. It was found that the subjects made two distinct kinds of judgment: predictive judgment and evaluative judgment. The factors influencing each judgment of quality and authority were identified in terms of characteristics of information objects, characteristics of sources, knowledge, situation, ranking in search output, and general assumption.

The University of Arizona Library is a vital participant in the AgNIC Rangelands project and has contributed to the initiative in many ways. For example, in the mid-to-late 1990â s the Library digitized the backfiles of the Journal of Range Management for open access on the web. Funding and completing digitization projects such as this is a complicated process and requires many decisions along the way. This paper outlines the process taken by the Library to manage a more recent project to scan back issues of the journal Rangelands. It starts with the decision to develop a project plan and request funding from the National Agricultural Library (NAL). It continues on to describe negotiating agreements with project partners, the process for outsourcing of scanning, the design of the technical infrastructure needed to support digitized content, and issues of sustainability that any digital library encounters.

In recent decades there has been a notable expansion of statistical data produced by the public and private sectors for administrative, research, policy and evaluation programmes. This is due to advances in relatively inexpensive and efficient data collection and management of computer-readable statistical data. Corresponding changes have not occurred in the management of data collection, preservation, description and dissemination. As a result, the process by which data become accessible to social researchers and others is frustrating, time consuming, and inefficient. This paper describes the reasons for this situation: the problem-solving workstyle of social data users, the nature of the data and their relationship to computer technology, and an inchoate social science information infrastructure. Since statistical data play an increasingly important role in social research and policy decisions, social science information specialists must be prepared to meet the computer-readable statistical data user's needs. Four strategies are recommended for improving utilization of these data: improving the quality of statistical evidence, educating information professionals and end-users in numerical information, using the existing information infrastructure to preserve and disseminate data, and developing retrieval tools for improving access to information about social data.

The intent of this article is to describe how the social science data library responds to requests for particular data when the data are not cataloged in the data library's collection. The author defines those activities undertaken to locate a potential resource as the pre-acquisition process. The pre-acquisition process begins when the library staff and client have been unable to locate relevant data in the library. Depending upon the nature of the request, time constraints imposed on the client (to produce an analysis based upon these data), and status of the client in the university setting, both staff and client undertake a search to locate the data the client needs. Together they examine the library's reference collection and literature in the field, seek information from experts in the field, and correspond with libraries and institutions which might potentially hold the data or be able to provide assistance in locating the data. The decision to undertake these activities during the preacquisition process depends upon a number of factors. They include the library's mandate regarding the nature of the collection and of its clientele, the level of flexibility in its policies, the quality of the staff, the degree to which the staff is committed to providing user services. the quality of its reference collection and services, and constraints on library resources. Although constraints on the library's resources may indeed be a major factor in determining whether to undertake a search and at what level and to what extent the services shall be provided, the first part of this article presents a brief description of only five factors: the nature of the collection, the impact of an acquisitions policy upon the preacquisition process, staff, the interaction between staff and client, and reference services." The second part describes the preacquisition process carried out at the Social Science Data and Program Library Service (DPLS) at the University of Wisconsin Madison as an illustration of locating data to meet a special client request. The author believes that a description of these activities should have utility not only for data libraries, but for other libraries for formalizing the process of meeting special requests.

The "collaboratory" concept has recently entered the vernacular of the scientific community to reflect new modes of scientific communication, cooperation and collaboration made possible by information technology. The collaborator represents a scientific research center "without walls" for accessing and sharing data, information, instrumentation and computational resources. The principal applications of the collaboratory concept have been in the physical and biological sciences, including space physics, oceanography and molecular biology. Discusses the attributes of the collaboratory, and applies the concept developed by computer and physical scientists to the design and operation of the SIPP ACCESS prototype information system for complex data to be used through the Internet by sociologists, demographers and economists. Examines obstacles to collaborator development for the social sciences. Concludes that four major obstacles will inhibit the development of collaboratories in the social sciences.

In an effort to assist medical researchers and professionals in accessing information necessary for their work, the A1 Lab at the University of Arizona is investigating the use of a natural language processing (NLP) technique called noun phrasing. The goal of this research is to determine whether noun phrasing could be a viable technique to include in medical information retrieval applications. Four noun phrase generation tools were evaluated as to their ability to isolate noun phrases from medical journal abstracts. Tests were conducted using the National Cancer Institute's CANCERLIT database. The NLP tools evaluated were Massachusetts Institute of Technology's (MIT's) Chopper, The University of Arizona's Automatic Indexer, Lingsoft's NPtool, and The University of Arizona's AZ Noun Phraser. In addition, the National Library of Medicine's SPECIALIST Lexicon was incorporated into two versions of the AZ Noun Phraser to be evaluated against the other tools as well as a nonaugmented version of the AZ Noun Phraser. Using the metrics relative subject recall and precision, our results show that, with the exception of Chopper, the phrasing tools were fairly comparable in recall and precision. It was also shown that augmenting the AZ Noun Phraser by including the SPECIALIST Lexicon from the National Library of Medicine resulted in improved recall and precision.

Despite the intensive revision carried out in the past two decades, there are still some outdated parts of UDC in need of attention. Although new terminology may be added on a more specific subject level, the outdated and illogical structure of the top classes in class 9 stands out. The work on recent extensions of class 94 History has reminded us of what is still wrong in the class 9.

The purpose of this study is to analyze the relationship between citation ranking and peer evaluation in assessing senior faculty research performance. Other studies typically derive their peer evaluation data directly from referees often in the form of ranking. This study uses two additional sources of peer evaluation data: citation content analysis and book review content analysis. Two main questions are investigated: (a) To what degree does citation ranking correlate with data from citation content analysis, book reviews, and peer ranking? (b) Is citation ranking a valid evaluative indicator of research performance of senior faculty members? Citation data, book reviews, and peer ranking were compiled and examined for faculty members specializing in Kurdish studies. Analysis shows that normalized citation ranking and citation content analysis data yield identical ranking results. Analysis also shows that normalized citation ranking and citation content analysis, book reviews, and peer ranking perform similarly (i.e., are highly correlated) for high-ranked and low-ranked senior scholars. Additional evaluation methods and measures that take into account the context and content of research appear to be needed to effectively evaluate senior scholars whose performance ranks relatively in the middle. Citation content analysis data did appear to give some specific and important insights into the quality of research of these middle performers, however, further analysis and research is needed to validate this finding. This study shows that citation ranking can provide a valid indicator for comparative evaluation of senior faculty research performance.

This paper discusses the development of the Polar UDC. It examines some elements of the UDC specific to the Polar context, in particular the geographical auxiliary schedule. Some future plans for the implementation of UDC in a library and also in a museum context are outlined.
