Background: It is unclear which terms should be included in bibliographic searches for randomized controlled trials (RCTs) of drugs, and identifying relevant drug terms can be extremely laborious. The aim of our analysis was to determine whether a bibliographic search using only the generic drug name produces sufficient results for the generation…

A high degree of constancy has been found in the microstructure of titles of samples of the INSPEC data base taken over a three-year period. Character and digram frequencies are relatively stable, while variable-length character-strings characterizing samples separated by three years in time show close similarities.

This is the seventh in a series of eight reports of a research study for the National Agricultural Library (NAL) on the effective utilization of bibliographic data bases in machine-readable form. The report addresses the problems of converting input data (in source formats) from various sources, both external and internal to NAL, to a common…

Europe's lag in databanks and online commercial availability is contrasted to its lead in numbers of bibliographic files. Intelligent use of new technologies such as Viewdata and the European Communications Satellite are expected to correct this imbalance. (RAA)

This is the second in a series of eight reports of a research study for the National Agricultural Library (NAL) on the effective utilization of bibliographic data bases in machine-readable form. It consists of two parts. The first part defines the basic interaction alternatives and subalternatives open to the NAL with respect to its interfacing…

Sixth in a series of eight reports of a research study for the National Agricultural Library (NAL) on the effective utilization of bibliographic data bases in machine-readable form, this report deals with the query language, search strategy and related considerations for a particular information storage and retrieval system. One section of the…

The formation of a single, correlated set of data elements, accomplished by merging sixteen commercial and national bibliographic data bases, and subsequent improvements in current awareness and information retrieval activities are described. The correlation is compatible with most existing and proposed data-element standards. (27 references)…

This study examines (1) subject content, (2) file size, (3) types of documents indexed, (4) range of years spanned, and (5) level of indexing and abstracting in five databases which collectively provide extensive coverage of the forestry and forest products industries: AGRICOLA, CAB ABSTRACTS, FOREST PRODUCTS (AIDS), PAPERCHEM, and PIRA. The…

A committee on rules fur cataloging machine readable data files (MRDF) recommends areas for revision of the Anglo American Cataloging Rules to integrate collections of MRDF into the mainstream of bibliographic control. The 12 working papers which support and detail these recommendations are appended to this report. They include rationales for…

This is the third in a series of eight reports of a research study for the National Agricultural Library (NAL) on the effective utilization of bibliographic data bases in machine-readable form. It consists of about 750 references collected to provide background data for the seven technical tasks of the study. The bibliography is set up to…

This is the fifth in a series of eight reports of a research study for the National Agricultural Library (NAL) on the effective utilization of bibliographic data bases in machine readable form. NAL desires ultimately to develop techniques of interacting with other data bases so that queries put to NAL may be answered with documents or document…

Two computer information systems, one for reference retrieval and the other for the retrieval of numerical data on atomic and molecular physics are being developed at the Queen's University of Belfast. The reference retrieval system is based on the atomic and molecular physics section of the INSPEC tapes. The tapes contain complete abstracts of…

This study examines the integration of heterogeneous bibliographic information resources from geographically distributed locations in an automated, unified, and controlled way using abstract data types called "classes" through the Message-Object Model defined in Smalltalk-80 software. The concept of achieving data consistency by…
