This article is based on a presentation given July 1, 1991, at the American Library Association's annual conference. It reports on an attempt to develop a CD-ROM price index modelled on the price indexes for serials and other materials produced under the aegis of ALA's Library Materials Price Index Committee and conforming to ANSI Standard Z39.20-1983. This proved to be an impossible task, primarily because of the inability to define a reliable unit of measurement for CD-ROM prices and the difficulty of tracking a sufficiently representative sample of the universe of CD-ROM titles purchased by libraries over the period from 1988–1991. However, the value of simply tracking the prices of a data sample without a base index year—a price inventory—was recognized by the Committee. The data gathered thus far were analyzed to show price trends by LC subject classification and publication types (monographs and serials). The 4.3% increase from 1989 to 1990 reflects the change from $1,783 to $1,860 in publication price for the average CD-ROM title. The evolution and stabilization of the CD-ROM publishing industry in the 1990s should support the eventual establishment of a CD-ROM price index, on which work continues.  相似文献

This work is an annotated bibliography that consists of articles, books, conference papers, dissertations, reports, etc. published in various library and information science forums on the subject of librarianship in the Maghreb. The goal of preparing this work is to provide a list of citations with abstracts that librarians, library students, and library scholars can use to perform research within this subject area and further the body of knowledge. The research methodology that was used to find these citations involved searching the database versions of ERIC, Dissertations Abstracts Online, and Library Literature within the online public access catalog of the Auburn University library system. It also involved searching the online databases of Library and Information Science Abstracts (LISA), British Education Index, andEducation Abstracts within the DIALOG database as well as the respective print versions of these resources. While this work is by no means an exhaustive critique of the entire Maghrebi library and information science literature, it does strive to be comprehensive in terms of its country-by-country analysis of librarianship and information science within the region. In providing a citation for a non-English language work, the English equivalent of the title of that work will be given next to the non-English title.  相似文献

Despite the long history of the dental hygiene profession, little research has been conducted on the characteristics of its literature. In this study, the bibliometric method was used to identify the core journals in the discipline and the extent of indexing of these journals. The study was a part of the Medical Library Association (MLA) Nursing and Allied Health Resources Section's project to map the allied health literature. Five journals were found to provide one-third of all references studied. Forty-two journals yielded an additional one-third of the references. MEDLINE had the best indexing coverage with 87% of the journals receiving indexing for at least one-half of the articles included. Limited coverage was provided by EMBASE/Excerpta Medica (11%) and the Cumulative Index to Nursing and Allied Health Literature (9%). The findings identified titles that should be added by indexing services as well as those that should have more complete coverage.  相似文献

Abstract

The University of Arizona Library, in conjunction with the United States Government Printing Office's Library Programs Service, worked to create a model for a virtual depository by replacing tangible documents with their online counterparts whenever possible. The partnership was achieved by dedicated teamwork: the UA team provided the searching and assessment; the GPO team provided the legal and organizational framework as well as the indexing. At the end of the pilot project's year the program was deemed to be a success and GPO and UA worked to make this process a more permanent one with positivelong-term effects in terms of costs and human and physical resources.  相似文献

There have been ample suggestions in the literature that terms added to documents from Flickr and Wikipedia can complement traditional methods of indexing and controlled vocabularies. At the same time, adding new metadata to existing metadata objects may not always add value to those objects. The potential added-value of using user-contributed (“social”) terms from Flickr and the English Wikipedia in image indexing is compared with using two expert-created controlled vocabularies—the Thesaurus for Graphic Materials and the Library of Congress Subject Headings—without those social terms. Experiments confirmed that the social terms did add value, relative to terms from the controlled vocabularies. The median rating for the usefulness of social terms was significantly higher than the baseline rating, but was lower than the ratings for the terms from the Thesaurus for Graphic Materials and the Library of Congress Subject Headings. Furthermore, complementing the controlled vocabulary terms with social terms more than doubled the average coverage of participants' terms for a photograph. The relationships between user demographics and users' perceptions of the value of terms were also investigated, as well as the relationships between user demographics and indexing quality, as measured by the number of terms participants assigned to a photograph. Participants with more tagging and indexing experience assigned a greater number of tags than did other participants.  相似文献

Library of Congress subject headings (LCSHs) are generally felt to be especially inadequate in dealing with social science materials. I attempted to see whether PRECIS indexing "brought out" what a group of urban studies works were "about" better than LC subject cataloging. PRECIS does turn out to provide more access points than LCHS; but this advantage would disappear in an on-line catalog having key-word access. PRECIS also ends up providing apt headings more of the time than LCSH; its advantage here, however, would diminish if LCSH (1) employed more up-to-date vocabulary and (2) included a time facet more freely. Neither LCSH nor PRECIS turns out to be particularly successful in dealing with "multi-tiered works," those whose "intellectual subject(s)" differ from their "ostensible subject(s)." I argue that the best way to provide good subject access to these (as well as many other kinds of) works would involve supplementing traditional subject headings with abstracts or summaries.  相似文献

In the preparation of a book on how to do a literature search, many inconsistencies were found in the assignment of subject terms. The Library of Congress Subject Headings is cited for not bringing computer languages into a consistent pattern. BASIC and FORTRAN are treated differently in their see also references and are without references to the words "computers" or "computer." Also index terms for the literature search on the "search for extraterrestrial life" showed inconsistent patterns in indexing. Catalogers and indexers need to review the work they are currently publishing and try to decide how to bring some standardization to the construction of subject terms. There is a need to provide a single thesaurus for all English index terms.  相似文献

Due in large part to the interdisciplinary nature of the profession, Home Economics reference collections are often difficult to develop, maintain, and assess. Collection development responsibilities are usually divided among several librarians across the broad spectrum of the social sciences, humanities, and applies sciences. To help ensure basic and balanced collections, a "core" bibliography of home economics reference sources is provided. The included works are listed alphabetically under the broad categories of "Indexes and Abstracts," "Dictionaries and Encyclopedias," and "Handbooks and Sourcebooks." This bibliography should be used as a starting framework for a basic home economics reference collection. Individual libraries might further develop specific subject areas to support their own institution's needs.  相似文献

The German National Library of Science and Technology (TIB) developed a Web-based platform for audiovisual media. The audiovisual portal optimizes access to scientific videos such as computer animations and lecture and conference recordings. TIB's AV-Portal combines traditional cataloging and automatic indexing of audiovisual media. The article describes metadata standards for audiovisual media and introduces the TIB's metadata schema in comparison to other metadata standards for non-textual materials. Additionally, we give an overview of multimedia retrieval technologies used for the Portal and present the AV-Portal in detail as well as the additional value for libraries and their users.  相似文献

Even before the creation of the American Library Association's Government Documents Round Table (GODORT) in 1972, librarians had long distinguished themselves as champions of the people's right of access to government information. In particular, it was the American Library Association's Public Documents Committee, which, during its long tenure from 1876 to 1956, remained the premier organizational body through which the library profession sought to shape government information policies. While the commitment of members of the Public Documents Committee to the goal of open access to government information never wavered, the underlying sense of mission that guided the Committee's work underwent considerable evolution during its history. Whether as genteel reformers of the Gilded Age, patriotic popularizers of the 1920s, or university-oriented social engineers during the Great Depression, Public Documents Committee members crafted a government documents reform agenda that translated a recognizably modern objective into the social and intellectual idiom of the age in which they lived.  相似文献
