Research report on subject heading patterns in OCLC monographic records by Edward T O'Neill( )

2 editions published in 1979 in English and held by 62 WorldCat member libraries worldwide

This investigation examines the characteristics of subject headings occurring in cataloging records. The study analyzes a sample of 33,455 monographic records taken from the OCLC database. The sample contained a total of 50,213 subject headings, 94% of which were Library of Congress (LC) subject headings. Each record had an average of 1.4 LC subject headings. However, 18.6% of the records did not have any LC subject heading assigned to them
Research report on analytical review of catalog use studies by Karen Markey( )

4 editions published in 1980 in English and held by 56 WorldCat member libraries worldwide

This review takes a critical approach in summarizing and evaluating the methodology and scope of catalog use studies, with emphasis on the subject approach to card catalog searching. Subject access is defined in this report; however, the process of subject searching, described repeatedly in library literature, has been based upon common sense understanding rather than systematic observation. The findings of catalog use studies are classified into: (1) generalizations on the physical format of the catalog, information found on the cards, catalog searchers' educational level or area of expertise, and reference assistance; (2) generalizations specific to subject searches, user characteristics, and the physical structure of the catalog; and (3) generalizations specific to known-item searches and nonstandard information, failure at the catalog, and author-title information. The major reviews of catalog use studies and their methods are also covered. A bibliography of catalog use studies and a cited author index are provided. (Author/RAA)

Research report on field, subfield, and indicator statistics in OCLC bibliographic records by Thomas Butler Hickey( Book )

2 editions published in 1981 in English and held by 9 WorldCat member libraries worldwide

The statistics that are presented are based on a one percent systematic sample of the oclc online union catalog as of January 1980. Detailed data were collected on the use of fields, subfields, indicators in bibliographic records, and on the co-occurrence of fields within bibliographic records. The sample used for the study was obtained by extracting all records with an oclc control number ending in 44. For each category of this report, the statistics are grouped by format: monographs, serials, audiovisuals, sound recordings, music scores, maps, manuscripts, and cumulative bibliographic files. These statistics should be useful for estimating file growth, selecting subsets of records for local catalogs, and for designing bibliographic record data bases. (Author/RAA)

Assessing Information on the Internet : Toward Providing Library Services for Computer-Mediated Communication. A Final Report by Martin Dillon( Book )

1 edition published in 1993 in English and held by 3 WorldCat member libraries worldwide

The Online Computer Library Center Internet Resource project focused on the nature of electronic textual information available through remote access using the Internet and the problems associated with creating machine-readable cataloging (MARC) records for these objects using current USMARC format for computer files and "Anglo-American Cataloguing Rules, Second Edition" (AACR2). Internet users gain access to files using the File Transfer Protocol (FTP) and the Simple Mail Transfer Protocol (electronic mail). During the time of this study, the number of FTP sites increased 25%; the number of files, 46%; and the amount of storage, 63%. Descriptive information associated with these files is scant. Source code and system code combined account for 43% of files and 49% of storage, while text files account for 10% of files and 8% of storage; other categories include news, personal computer programs, data files, computer images, computer games, and executable program files. A test of the USMARC format for computer files and the AACR2 rules revealed that some extensions are necessary to accommodate remotely accessed electronic objects. A new MARC field, electronic location and access, is proposed. Draft cataloging guidelines to assist in the application of existing rules are offered. Twelve figures and 18 tables present study findings. Five appendixes include additional information about Internet and a 410-item annotated bibliography. (SLD)

Functional Specifications for the Oclc Interlibrary Loan Subsystem by Phyllis V Bova( Book )

1 edition published in 1977 in English and held by 3 WorldCat member libraries worldwide

This report covers functional specifications for the oclc Interlibrary Loan (ill) Subsystem, designed to permit participating libraries to increase the availability of library resources to patrons by enabling these libraries to form, transmit, and fulfill loan requests more rapidly and effectively. It will provide rapid access to a large on-line union catalog containing bibliographic data and location listings. Specifications described are definition of on-line files, authorization levels, definition of on-line ill record--including a chart specifying fields, lengths, input and instruction; searching the file, user workflow at the terminal, summary of user commands, and system messages.

Modeling and evaluation of on-line user behavior : final report to the National Library of Medicine by William David Penniman( Book )

1 edition published in 1981 in English and held by 2 WorldCat member libraries worldwide

This investigation of search patterns associated with the medline database had four primary objectives: (1) to refine the stochastic process method of evaluating user behavior; (2) to examine user search behavior exhibited when selecting documents sets; (3) to identify factors that affect the patterns of user behavior; and (4) to use data from the National Library of Medicine (nlm) medline system to develop a model of ineffective user behavior. Samples of online session protocols obtained from NLM's online system elhill-3 were processed in three major phases: the recovery of individual medline user sessions from the transaction tapes, parsing the individual user and system transactions to assign a unique activity code, and the analysis of user/system behavior using the parsed sessions. The data obtained were analyzed by user id, daily usage, and level of activity, as well as selected variable analysis and fragment analysis. Findings are outlined and compared with prior studies, and the results of data analyses are summarized for each of seven hypotheses. The methodology and results are detailed, and a need for additional research in the area of search effectiveness is indicated. Twenty references are listed. (Raa)
End user behavior on the Ohio State University Libraries' online catalog : a computer monitoring study by Christine L Borgman( Book )

1 edition published in 1983 in English and held by 2 WorldCat member libraries worldwide

This report describes a computer-monitoring study of users of the Ohio State University Libraries' online catalog, an established and heavily used information retrieval system. Designed for end users, online library catalogs require little or no formal training, and often replace an existing manual system. Data were gathered unobtrusively by monitoring all transactions from 45 terminals on 5 of the Ohio State University campus libraries. The terminals were monitored online for 3 weeks in each of the winter, spring, and autumn terms and 2 weeks of the summer term 1981, and observation data were used to define user sessions. The study characterizes user behavior in terms of types of searches done, patterns of use, time spent on searching, errors, and system problems. Preliminary results suggest that users have much shorter sessions on online-catalog systems than on other types of retrieval systems. Patterns of use vary between campus libraries, academic quarters, and between short and long sessions. Results of the study will be applied to improving the user interface and other system features.

Nonfiction Book Use by Academic Library Users. Research Report-88/1 by Chandra G Prabha( Book )

2 editions published in 1988 in English and held by 2 WorldCat member libraries worldwide

This investigation of the use of nonfiction books borrowed from an academic library--the Main Library at the Ohio State University--examined two premises which underlie the creation of full-text electronic information systems of nonfiction books: that such books are generally read to obtain information, and that they tend to be read in parts. Data were also collected on the methods users employed for selecting nonfiction books and the features of the book that were used to find information. Interviewing slots were randomly selected from two-hour time periods during library operation hours, and 426 users returning their nonfiction books during these slots were interviewed between February 2 and March 8, 1987. Overall, the findings largely supported the premises under study. They indicated that 23.2% of the nonfiction book users needed the book for school, read one-fourth of the book or less, and used the table of contents or book index to find information. It was concluded that nonfiction books seem appropriate candidates for electronic access if directed at this subgroup of users in an academic environment. Data are reported in 34 tables and four figures. Appendixes include the interview script, an explanation of estimating the number of users missed by the interviewers, and the randomization methods used. (5 references) (cgd)
Technical Report on Processing Centers by Carl A Anderson( Book )

1 edition published in 1980 in English and held by 2 WorldCat member libraries worldwide

The main instrument of data collection in this survey of library technical processing centers was a questionnaire sent to 16 network coordinators. Following a review of current literature, results of the questionnaire are discussed with regard to five areas: (1) each network's means of identification (definition) of processing centers, (2) types of clients served, (3) means by which libraries became clients, (4) charges levied, and (5) needs of processing centers for continuing access to cataloging data. Each network's definition of a processing center is presented; statistical tables present data from the other four areas of concern from the questionnaire. Information from "Totcat Network Billings" supports a discussion on system use data. Tables are used to show system activity of institution, proportions of first time uses, distribution of titles produced, and other information. In the next section, a table lists 32 commercial processing centers and indicates which of four standard services are available through each (book catalog services, book processing kits, cataloging services, or printed catalog cards). Appendices containing the processing center questionnaire and cover memorandum, an essay on the state-of-the-art of processing centers in Wisconsin, and network billing data complete the report. (Sw)
The nationwide network and OCLC : a vision and a role by Rowland C. W Brown( Book )

1 edition published in 1986 in English and held by 2 WorldCat member libraries worldwide

Before turning to the OCLC vision of nationwide networking, a review of some of the issues that have influenced that vision are presented, including: technology as a driving force; library and information economics; the challenge of providing ever-proliferating services to an ever more computer-literate end user; the changing role of the library itself--in the university, college, municipality, or school system, and in the professions; the increasing role of commercial enterprises; and the increasing number of technology-driven local options and local cost-benefit considerations that ignore networking in a national resource-sharing environment. The paper then examines the OCLC vision of future networking in the face of strong decentralizing forces including: the continued development of "networks of networks" in the United States that create a nationwide network with no monolithic structure; greater cooperation and resource-sharing among the bibliographic networks; changes in networking concepts to accommodate technological change; and specific efforts that must be made at every level in the library and education community. Finally, OCLC's vision of national and international resource-sharing projects and their role in the future is discussed in light of directions set by the OCLC charter. A short list of references is included. (THC)
Dewey decimal classification online project interim reports to the Council on Library Resources, April 1984, September 1984, and February 1985 by Karen Markey( Book )

2 editions published in 1985 in English and held by 2 WorldCat member libraries worldwide

This research project focuses on the implementation and testing of the Dewey Decimal Classification (ddc) system as an online searcher's tool for subject access, browsing, and display in an online catalog. The research project comprises 12 activities. The three interim reports in this document cover the first seven of these activities: (1) obtain documentation and selected portions of ddc from Inforonics and experiment with this ddc in a machine environment; (2) share the results of Activity 1 with library representatives, ddc editor, Forest Press, consultants, and Council on Library Resources (clr) Project Monitor and obtain their recommendations for ddc fields and text for subject access, browsing, and display in an online public access catalog (opac); (3) evaluate recommendations of Activity 2 with ddc editor and other concerned parties to determine ddc fields and text for subject access, browsing, and display in an opac; (4) obtain participating libraries' bibliographic records in classification areas of interest; (5) index each library's bibliographic records in ways characteristic of online catalogs; (6) design, test, and implement software to provide subject access, browsing, and display of the ddc in the opac; and (7) design, pretest, and refine research design, experimental procedures, post-search interview instruments, and sample searches. Numerous appendices include a version of the Dewey Online Catalog for review, lists of reviewers, their comments, and questionnaires and worksheets. (Thc)
