The technique for machine-aided indexing developed at the Defense Documentation Center (DDC) is illustrated on a randomly chosen abstract. Additional text is provided in coded form so that the reader can more fully explore this technique. (2 references) (Author)

The problems of using English for information retrival are delineated. The querying capability of a keyword dialog system is illustrated with actual computer output. Major advantages of this approach are: reduced ambiguity in requests, users may think in smaller functional units, and users may edit previous requests. (7 references) (Author/SJ)

A design method for information retrieval systems, based on a modelling technique, and derived from the general objectives and tasks set for the system is described. (12 references) (SJ)

This article discusses the development of social science data archives and services in Canada, the objectives and management of a clearinghouse, and the regional and provincial arrangements for social science data services. (SJ)

Among the data described are infrared indexes, mass spectral data, chromatographic data, X-ray emmission data, odor and taste threshold data, and thermodynamics data. This paper provides the chemical documentarian a complete reference source to a wide variety of analytical data. (Author/NH)

The New York Times" Information Bank is described in detail. Scheduled to be in operation in 1972, this project makes available abstracts of newspaper articles for on-line search and retrieval, combined with microform copies of the original articles. (Author)

Discusses the objectives in constructing a centralized and computerized data bank for a school system and the uses to which such a bank could be put. (LS)

A comparison of records for 217 serial titles (holdings reports, selected bibliographic data elements, supplementary notes) found in both the OCLC online database and "New Serial Titles" (NST) indicates that OCLC is superior resource for current material, while NST is stronger resource for older titles. Five references are included. (EJS)

Tests performed on 6,260 titles from 3 machine-readable British National Bibliography files using an entropy based technique for abbreviation of text strings for use as a control code found that more than 94 percent of the titles generated a unique seven character code. Six references and an illustrative example are appended. (EJS)

Discusses categorization of MARC records, noting problems which arise because formats have not been defined as distinct sets of content designators. Bibliographic and authority record formats, merging of formats into single format, removal of inconsistencies, and criteria for identifying categories of records are considered. Thirty-one references…

The Spelling Error Detection Correction Project completed at Chemical Abstracts Service, which extracted over 50,000 misspellings from approximately 25,000,000 words of scientific and scholarly text, shows that expected incidence of misspelling is 0.2 percent, and most misspellings are "typos," 90 percent of which are unlikely to be…

Discusses database design concept termed "normalization" (process replacing associations between data with associations in two-dimensional tabular form) which results in formation of relational databases (they are to computers what dictionaries are to spoken languages). Applications of the database in serials control and complex systems…

This working paper from the American National Standards Committee Z-39, Subcommittee G on Standard Terms, Abbreviations and Symbols for Use in Interactive Information Retrieval discusses the issue of standardization for command languages used in interactive online searching of bibliographic databases.
