This manual familiarizes data users with the procedures followed for data collection and processing of the high school transcript component of the National Education Longitudinal Study of 1988 (NELS:88). A second objective is to provide the necessary documentation for using the data files. Chapter 6 and appendix F, in particular, contain…

The Vocational Education Data System (VEDS) data base was created as a result of the Vocational Education Amendments of 1976. VEDS statistics were to be collected in the form of state-aggregate data (that is, state-level data is submitted by each state, based upon records and data collected by the state for this and other purposes); and VEDS data,…

Nine tables are provided. (RBF)

This report describes the composition and operation of the library of the Gray Freshwater Biological Institute at the University of Minnesota, a non-traditional information service which provides information to the institute by combining the use of three bibliographic databases with current awareness services, OCLC, MINITEX, and author reprint…

This report presents an information needs assessment for an office automation plan to be undertaken for the School Building Services Branch of the Alberta Department of Education. This exercise complements the work of two senior committees within the Department: (1) the Electronic Information Processing Needs Study Steering Committee, and (2) the…

Two tables compare projected costs of online versus offline retrieval of citations from 50 databases using BRS and DIALOG. Data include database; databank; cost of access per hour; cost of 15-minute search with no retrieval; and cost of 15-minute search plus cost of 10 and 30 online or offline citations. (CLB)

This paper considers the processing of digital library queries, consisting of a text component and a structured component in distributed environments. The paper concentrates on the processing of the structured component of a distributed query. A method is proposed to identify the databases that are likely to be useful for processing any given…

Exploring the use and effectiveness of current awareness (CA) methods, especially selective dissemination of information (SDI) among chemists at Canadian universities, this study focuses on the perceived dispersal of information, use of various CA methods, time spent on CA, perceived success in CA, and CA efficiency. (FM)

Describes method of generating Electronic Yellow Pages mailing labels using DIALOG commands which involve downloading to disk and interposing a BASIC language program between disk and printer. Downloading problems (accession numbers, "tic" which DIALOG provides, line noise), two versions of program (full, compressed), and output examples…

Discussion of users and information retrieval systems highlights a study that investigated the representation of users' knowledge by examining their names for objects and concepts, agreement on names, the Library of Congress Subject Headings representation for similar objects and concepts, and measurement of the similarity between these…

This codebook describes the data file used in a study which gathered data on 80 presearch interviews in seven medical libraries.

Three papers based on projects produced in a course entitled Operations Research and Library Management, jointly sponsored by the Department of Mechanical and Industrial Engineering and the Graduate School of Library Science are reported and explained. Topics covered include an assessment of faculty interest in an information retrieval service;…

In 1981 and 1982, a group of 5 organizations conducted a coordinated study of public online catalog users and nonusers in 31 research, academic, community college, public, and governmental libraries with 17 different online catalogs. It was found that: (1) the most important user characteristic linked with success and satisfaction in using online…

Over the last decade, studies of online catalogs have revealed that they frequently discourage users. Subject queries often fail to produce retrievals or produce retrieval sets that are too large and unwieldy to be easily scanned. Research shows that users are seeking alternative approaches to those that manipulate the subject headings in catalog…
