We read with considerable interest the study by Gusenbauer and Haddaway (Gusenbauer and Haddaway, 2020, Research Synthesis Methods, doi:10.1002/jrsm.1378) comparing the systematic search qualities of 28 search systems, including Google Scholar (GS) and PubMed. Google Scholar and PubMed are the two most popular free academic search tools in biology…

Discusses the basic principles of the application of microfilm (analog) and electronic (digital) technologies for data storage. Image quality is examined, searching and retrieval capabilities are considered, and hardcopy output resolution is described. It is concluded that microfilm is still the preferred archival medium. (5 references) (LRW)

Discusses problems in creating the information retrieval mechanisms used in constructivist computer-based learning environments to support knowledge discovery: (1) subject can not always be pre-specified and the learner may not know what to seek; (2) retrieval strategies differ considerably from conventional ones, with the search including data,…

Describes six leading numeric databank services and compares them with bibliographic databases in terms of customers' needs, search software, pricing arrangements, and the role of the search specialist. A listing of the locations of the numeric databanks discussed is provided. (CLB)

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)…

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. (CLB)

Describes a study that investigated search strategies for electronic encyclopedias by observing search activities in a high school media center where students used "The Grolier Multimedia Encyclopedia." The teacher's role, the role of the librarian as teacher and as facilitator, student use of electronic resources, and basic skills for…

Provides a novice's guide to locating and using patent resources on the Internet. The guide examines how easily a novice can find and use patent resources, and evaluates resources on their search and retrieval capability. Findings are from the author's own experiences with various online services and are presented as personal narratives. (JMV)

Discusses approaches to the integration of query-based information retrieval and browsing in a hypertext network. A prototype system developed to evaluate the proposed approach in terms of retrieval effectiveness and search efficiency is presented, and design and implementation issues concerning the prototype are considered. (30 references) (EA)

Discusses databases available for online searching in the humanities fields and describes searches that investigated scatter (i.e., the spread of subject terms across the databases), overlap among online files in terms of retrieved records, and the comparative effectiveness of natural language versus controlled vocabulary for information…

Several reference librarians respond to the Hernon and McClure study on the accuracy of library reference services. Highlights include problems with the methodology used (unobtrusive observation), and performance factors not addressed by the study. Comments by Hernon and McClure address these responses and ways to improve reference services are…

This review takes a critical approach in summarizing and evaluating the methodology and scope of catalog use studies, with emphasis on the subject approach to card catalog searching. Subject access is defined in this report; however, the process of subject searching, described repeatedly in library literature, has been based upon common sense…

POPLINE, a cooperatively produced bibliographic retrieval system offered through MEDLARS, is a comprehensive collection of the worldwide literature on population and family planning. A comparison of several medical and social science databases with POPLINE indicates that POPLINE offers the greatest depth and breadth of subject coverage in this…
