An analysis of pricing policies and costs of LEXIS and WESTLAW indicates that it is less expensive to subscribe to both using a PC microcomputer rather than a dedicated terminal. Rules for when to use each database are essential to lowering the costs of online legal research. (EM)

Compares the performance of ABI/INFORM on the DIALOG, NEXIS and DIALCOM systems in terms of documentation, database and system design, convenience, and cost. Examples of searches on the various systems are given. (CLB)

Discusses alternatives to the Boolean system that would enable users of online bibliographic databases--primarily those containing scientific and technical information--to obtain their required level of performance at lowest cost. Highlights include recall and precision factors (natural and controlled language, titles, abstracts, quorum function)…

This study tracks the increasing use of the term "information broker" in the professional library literature, and looks at the extent to which the professional literature reflects the increasing trend of information commodification. The content of three online databases was analyzed: LIBRARY LITERATURE, LISA, and ABI/INFORM. Four terms…

Presents overview of NEXIS, an online computer system providing access to the full text of magazines, newspapers, and wire services relevant to public affairs, social science, business, and general news. Describes free text search techniques, system features, and costs. A special NEXIS terminal has been developed by Mead Data Center. (RBF)

Shares information gathered from a three-day librarian conference in Monterey, California. Compares and contrasts several search engines and offers tips for effective searching. Discusses the efficacy and legality of censorware and how to stay employed during times of cutbacks and downsizing. (AEF)

Simply typing in a word or two will not "automagically" produce good results on the Internet. Choosing the shortage of school administrators as a topic, this article outlines search techniques (including Boolean logic), reveals major Web sites' reactions to those techniques, and outlines tricks for improving search results. (MLH)

Explores similarities between research approaches characterizing different paradigms in information science and different information-processing styles of individual researchers. Proposes a model of the way in which new knowledge is generated, based on these similarities. The model focuses on "research pathologies," and ways in which the…

The purpose of the present study is twofold: (a) to compare the validation of percentage of nonoverlapping data approach and percentage of data points exceeding the median of baseline phase (PEM) approach, and (b) to demonstrate application of the PEM approach in conducting a quantitative synthesis of single-subject research investigating the…

In order to determine whether the expertise of professionals in the field of psychiatry and law could be enhanced by the use of current awareness databases in addition to traditional online sources, the first of two papers in this document examines online searches on topics of interest to professionals in the psychiatry/law specialty. The use of…

Traditional library skills have been augmented since the introduction of online computerized database services. Because of the complexity of the field, forensic psychology can benefit enormously from the application of comprehensive bibliographic search strategies. The study reported here demonstrated the bibliographic results obtained when a…

The database contents, search features, and costs of two services offered by UTLAS (University of Toronto Library Automation Systems) are compared to determine which of the two should be used for interlibrary loan (ILL) processing at Concordia University. A review of studies of CATSS (Catalogue Support System) is provided, as well as a description…

The project described is a renewal of earlier work on Individualized Instruction for Data Access (IIDA), a program designed at Drexel University to aid users in searching a database with the computer acting as assistant. This quarterly report discusses the evaluation of IIDA through user interaction. Two types of evaluation were performed:…

Discusses the probabilistic nature of information retrieval, and describes a front end system designed to permit searchers to attach probabilistically interpreted weights to query terms, which could be adapted for conventional information retrieval systems without requiring radical changes in current indexing procedures. (37 references) (CLB)

Briefly describes DIALOG OnDisc and gives an example of an actual search of the ERIC database using this system. The screen displays and search commands are used to illustrate the differences between the easy menu search method provided for novice users and the command search method provided for experienced users.
