Reviews of literature are conducted within academia to summarize and highlight gaps in findings and research approaches associated with a particular line of inquiry. Identifying sources to be included in reviews in rigorous ways can be challenging for interdisciplinary research topics, as relevant articles may be found in a wide variety of…

When searching for scholarly documents, researchers often stick with the same familiar handful of databases. Yet, just beyond these limited horizons lie dozens of alternatives with which they could search more effectively, whether for quick lookups or thorough searches in systematic reviews or meta-analyses. Searchsmart.org is a free website that…

Acquiring research skills is considered to be a highly challenging aspect of developing expertise in the social sciences. Because instruction and mentoring in these skills are typically grounded in the self-report of researchers, difficulties in learning the material may be due to the content and accuracy of these explanations. Using a…

Bradford's Law has been the subject of much discussion and analysis in library and information science since its formulation in the 1930s and remains frequently debated to this day. It has been applied to various practices within the discipline, especially with regard to collection development, but its relevance to researchers and the potential it…

Investigates techniques for automatic coding of English language strings which involve titles drawn from bibliographic files, but do not require prior knowledge of source. Coding methods (basic, maximum entropy principle), results of test using 6,260 titles from British National Bibliography, and variations in code element ordering are…

Describes a microcomputer-based string index format generated from concept networks using multiple search terms. Link weighting is highlighted as a method to decide which term appears first so the entry reflects the classification implied by the search specification. The computer software used for this system is briefly described. (Author/LRW)

Proposes that the development of document-retrieval systems can benefit from the incorporation of conceptual modeling techniques, specifically classification, aggregation, and generalization. An array model is presented which has been designed especially for document retrieval. (Author/EM)

Presents system for automatic handling of ordered sets, states based on these sets, and differing points of view regarding Universe of Discourse. Aspects are represented by new logical "overlap" function with examples taken from Ranganathan's horse and carriage parable and several books involving four main concepts (history, geography,…

The absence of a central database and use of specialized language hinder nonexperts in becoming familiar with the science teaching and learning literature and using it to inform their work. The challenge of locating articles related to a specific question or problem, coupled with the difficulty of comprehending findings based on a variety of…

Very briefly describes a workshop on film and television documentation that informed participants about available reference and resource materials for information about films and television shows. (CLB)

Discusses the potential of recent work in artificial intelligence, especially expert systems, for the development of more effective information retrieval systems. Highlights include the role of an expert bibliographic retrieval system and a prototype expert retrieval system, PROBIB-2, that uses MicroProlog to provide deductive reasoning…

Provides overview of Ergonomics Abstracts Retrieval System (EARS), an online bibliographic search and retrieval system in the area of human factors engineering. Other online systems are described, the design of EARS based on inverted file organization is explained, and system expansions including a thesaurus are discussed. (Author/LRW)

Designed to measure end-users' efficacy in online searching based on their presearch experience with printed literature retrieval systems for the search topic, this experiment examined differences between manual searches preceding electronic searches and vice versa. The results were not statistically significant due to the small sample size.…

Presents a general mathematical framework for information retrieval, in which query evaluation is seen as a mapping from the free term algebra built by query descriptors and weights to the semantic algebra of evaluation value. Competing mathematical models that try to describe how retrieval systems behave are reviewed. (Author/MBR)

Describes three types of literature searches conducted as part of instructional design process: instructional materials, content research, and instructional theory reviews. Search techniques to complete each type of literature search are reviewed: card catalog, online, materials indexes, and grapevine searches. An example of an instructional…
