Discusses the need for computer assisted strategies to search multiple databases. A method is presented in which a pool of predefined searches is set up and a strategy is developed to identify an optimal search path. The application of this method is illustrated using a search carried out in seven databases. (11 references) (CLB)

Defines corporate family searching as the act of using computerized databases to identify a parent company and all of its related companies. Business databases available on Dialog that can be searched to trace a corporate family are identified and appropriate search strategies are described. (CLB)

A comparison of ERIC and LISA (Library and Information Science Abstracts) indexing of the three journals--Online, Online Review, and Database--revealed some differences but more similarities in number of terms per article and concepts per article. A vocabulary which distinguished the field of online searching did emerge. (Author/EM)

Reviews three database systems available for searching generic chemical structure representations: (1) Derwent's Chemical Code System; (2) IDC's Gremas System; and (3) Derwent's Markush DARC System. Various types of searches are described, features desirable to users are discussed, and comparison searches are described that measured recall and…

Analyzes data from quarterly surveys of vendors to determine revenues and usage of government databases and identify those receiving high revenues and high usage. It is concluded that the current decline in their market share is due to increasing numbers of databases from the private sector rather than actual usage. (EM)

Describes study that compared the costs of online searching on six databases in four systems.

Presents a new model of searching in online and other information systems, and reviews the literature of manual information seeking behavior for suggestions of capabilities users might like in online systems. Based on the model--called "berrypicking"--and research, suggestions are made for how new search capabilities could be implemented…

Describes the availability of databases held on DIALOG, ESA-IRS, and DATA-STAR. Database overlap among the systems, prices, database contents, and data transmission costs are addressed; and results of a search of the ENVIROLINE database on each system are presented.

A survey of business librarians at schools offering graduate degrees in business showed that: (1) most librarians search databases other then those related to business subjects; (2) most searches are for citations to articles; (3) most searches are paid for on a cost recovery basis; and (4) most librarians do searches for off-campus patrons.…

This study compares results of searching full text of journal articles available on standard inverted file systems with searching of various parts of a document's surrogate. Relative recall and precision ratios for four search methods (full text, abstract, controlled vocabulary, bibliographic union) are reported. Search topics are appended. (14…

Provides a checklist of functions and capabilities of online searching systems that attempts to cover all system features, not just searching functions. The checklist is suggested as a tool for checking features of new systems, as a framework for comparing systems, and as a source of suggestions for developing new online systems. (10 references)…

Reviews developments and products in the information industry that are aimed at the end user and identifies impediments to end user searching that may explain why end user access has not supported these products. Suggestions for overcoming these impediments are offered. (eight references) (CLB)

Discussion of online searching in the humanities focuses on a comparison of the retrieval from two databases which cover philosophical materials, Philosopher's Index and FRANCIS.
