  Gore, E. ; Bitta, M.D. ; Cohen, D.: ¬The Digital Public Library of America and the National Digital Platform.
  In: D-Lib magazine. 23(2017) nos.5/6, xx S.
  
  Abstract: The Digital Public Library of America brings together the riches of America's libraries, archives, and museums, and makes them freely available to the world. In order to do this, DPLA has had to build elements of the national digital platform to connect to those institutions and to serve their digitized materials to audiences. In this article, we detail the construction of two critical elements of our work: the decentralized national network of "hubs," which operate in states across the country; and a version of the Hydra repository software that is tailored to the needs of our community. This technology and the organizations that make use of it serve as the foundation of the future of DPLA and other projects that seek to take advantage of the national digital platform.

  Neuhaus, C. ; Marx, W. ; Daniel, H.-W.: ¬The publication and citation impact profiles of Angewandte Chemie and the Journal of the American Chemical Society based on the sections of Chemical Abstracts : a case study on the limitations of the Journal Impact Factor.
  In: Journal of the American Society for Information Science and Technology. 60(2009) no.1, S.176-183.
  
  Abstract: The Journal Impact Factor (JIF) published by Thomson Reuters is often used to evaluate the significance and performance of scientific journals. Besides methodological problems with the JIF, the critical issue is whether a single measure is sufficient for characterizing the impact of journals, particularly the impact of multidisciplinary and wide-scope journals that publish articles in a broad range of research fields. Taking Angewandte Chemie International Edition and the Journal of the American Chemical Society as examples, we examined the two journals' publication and impact profiles across the sections of Chemical Abstracts and compared the results with the JIF. The analysis was based primarily on Communications published in Angewandte Chemie International Edition and the Journal of the American Chemical Society during 2001 to 2005. The findings show that the information available in the Science Citation Index is a rather unreliable indication of the document type and is therefore inappropriate for comparative analysis. The findings further suggest that the composition of the journal in terms of contribution types, the length of the citation window, and the thematic focus of the journal in terms of the sections of Chemical Abstracts has a significant influence on the overall journal citation impact. Therefore, a single measure of journal citation impact such as the JIF is insufficient for characterizing the significance and performance of wide-scope journals. For the comparison of journals, more sophisticated methods such as publication and impact profiles across subject headings of bibliographic databases (e.g., the sections of Chemical Abstracts) are valuable.

  Plummer, K.A.: Mathematics subject headings for the PreK-12 community: a comparison of key terms from the National Council of Teachers of Mathematics (NCTM) Mathematics Standards to ERIC Thesaurus descriptors and the Library of Congress Subject Headings.
  In: Cataloging and classification quarterly. 42(2006) no.2, S.59-73.
  
  Abstract: The National Council of Teachers of Mathematics (NCTM) is an international organization which supports the teaching and learning of mathematics for children from Pre-Kindergarten through Grade 12. In the year 2000, the NCTM produced Principles and Standards for School Mathematics; a document that has become the basis for state and local mathematics curriculum standards across the United States. This article examines the key terms identified in the NCTM standards, identifies their equivalents in the ERIC Thesaurus and the Library of Congress Subject Headings, and makes recommendations to bring library subject headings closer to reflecting the language common to mathematics educators.

  Yi, K. ; Beheshti, J. ; Cole, C. ; Leide, J.E. ; Large, A.: User search behavior of domain-specific information retrieval systems : an analysis of the query logs from PsycINFO and ABC-Clio's Historical Abstracts/America: History and Life.
  In: Journal of the American Society for Information Science and Technology. 57(2006) no.9, S.1208-1220.
  
  Abstract: The authors report the findings of a study that analyzes and compares the query logs of PsycINFO for psychology and the two history databases of ABC-Clio: Historical Abstracts and America: History and Life to establish the sociological nature of information need, searching, and seeking in history versus psychology. Two problems are addressed: (a) What level of query log analysis - by individual query terms, by co-occurrence of word pairs, or by multiword terms (MWTs) - best serves as data for categorizing the queries to these two subject-bound databases; and (b) how can the differences in the nature of the queries to history versus psychology databases aid in our understanding of user search behavior and the information needs of their respective users. The authors conclude that MWTs provide the most effective snapshot of user searching behavior for query categorization. The MWTs to ABC-Clio indicate specific instances of historical events, people, and regions, whereas the MWTs to PsycINFO indicate concepts roughly equivalent to descriptors used by PsycINFO's own classification scheme. The average length of queries is 3.16 terms for PsycINFO and 3.42 for ABC-Clio, which breaks from findings for other reference and scholarly search engine studies, bringing query length closer in line to findings for general Web search engines like Excite.

  Vizine-Goetz, D. ; Hickey, C. ; Houghton, A. ; Thompson, R.: Vocabulary mapping for terminology services.
  In: http://jodi.tamu.edu/Articles/v04/i04/Vizine-Goetz/.
  
  Abstract: The paper describes a project to add value to controlled vocabularies by making inter-vocabulary associations. A methodology for mapping terms from one vocabulary to another is presented in the form of a case study applying the approach to the Educational Resources Information Center (ERIC) Thesaurus and the Library of Congress Subject Headings (LCSH). Our approach to mapping involves encoding vocabularies according to Machine-Readable Cataloging (MARC) standards, machine matching of vocabulary terms, and categorizing candidate mappings by likelihood of valid mapping. Mapping data is then stored as machine links. Vocabularies with associations to other schemes will be a key component of Web-based terminology services. The paper briefly describes how the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) is used to provide access to a vocabulary with mappings.

  Houston, J.E.: Thesaurus of ERIC (Educational Resources Information Center) descriptors : 14th ed..
  Westport, CT : Oryx Press, 2001. XXXV,731 S S.
  ISBN 1-57356-330-7
  
  Abstract: The Thesaurus of ERIC Descriptors, 14th Edition 2001, has been developed under the auspices of the Educational Resources Information Center (ERIC) of the National Library of Education, Office of Educational Research and Improvement (OERI), U.S. Department of Education. Its content reflects ERIC's 34 years of monitoring the educational literature. This 14th edition is the result of ERIC's continued efforts to maintain quality in its controlled vocabulary and to respond to the changing nature of education. As in previous editions, the Thesaurus reflects ERIC's response to the needs of the educational user community. ERIC remains committed to maintaining a Thesaurus that represents the definitive vocabulary for education. The 2001 edition contains 10,773 vocabulary terms, of which 5,963 are main-entry Descriptors and 4,810 are non-indexable USE references or "Dead" terms. New terms not appearing in previous editions include 206 Descriptors and 210 USE references. This edition also reflects several hundred Scope Notes and Cross-reference modifications to earlier Descriptor displays. Again as in the past, the Thesaurus revision has been made possible by the joint efforts and sound judgments of personnel throughout the entire ERIC system responding to both the literature and the users in the field. ERIC vocabulary coordinators, who, as members of the systemwide "Vocabular Review Group," oversee this effort, are listed below.

  Burchinal, L.G.: ¬The tale of two ERICs : factors influencing the development of the first ERIC and its transformation into a national system.
  In: Journal of the American Society for Information Science. 51(2000) no.6, S.567-575.
  
  Abstract: This article describes how the original ERIC was established as a conventional, centralized information center within the Office of Education in 1964, and how this initial ERIC was transformed from into a decentralized national system about 18 months later. The history of the two ERICs also illustrates how knowledge and expertise - in this case, that represented by advances in information systems technology and its applications - combined with interpersonal relationships within a bureaucracy, federal funding decisions, and organizational changes to shape the development of a major national information service. The time period covered by the article is from 1959, when planning for the first ERIC began, to June 1967, when the decentralized system became fully operational. Most of the description and analysis, however, is limited to the 1965-66 period, when the decentralized system was conceptualized and implemented. Important developments in ERIC since 1967 are also described

  In: Reference librarian. 1996, no.53, S.105-112.
  
  Abstract: From Sep 88 to Oct 90, Houston Cole Library, Jacksonville State University, Alabama, spent $ 4.852 for search fees for ERIC online. The popularity of the service was the stimulus to locate funds to purchase a workstation for ERIC on CD-ROM. The availability of a University faculty research grant provided the opportunity to fund the workstation and perform a research project during the transition. Describes a study comparing the ERIC print index, Resources in Education, to the ERIC Index in CD-ROM format. The study contrasts the 2 formats in the areas of accuracy of results, time savings and user satisfaction

  Fiscella, J.B. ; Proctor, E.: ¬An approach to assessing faculty use of locally loaded databases.
  In: College and research libraries. 56(1995) no.5, S.446-458.
  
  Abstract: Reports results of a study, conducted at Illinois University at Chicago, of faculty use of, preferences for, and satisfaction with either the SPIRS/Prism ot he BRS MENTOR interfaces for their locally loaded ERIC online database. Compare selected features of the 2 interfaces and differences in searching techniques. Presents a detailed comparison of satisfaction ratings, including non use, for 11 system functions (such as author searching and combining sets). Findings showed no significant faculty preference for either specific interface, however, a year after the database became available, the few faculty who did show a preference chose the customised BRS MENTOR interface. The study also studied use of other locally loaded databases by faculty in education and other social science disciplines. Addresses the limitations of the survey

  Diodato, V. ; Henry, G.: ¬The rates of assignment of narrower terms in the Thesaurus of ERIC Descriptors.
  In: Journal of information science. 19(1993), S.137-141.
  
  Abstract: Is there a link between the use of an indexing term and its physical similarity to its narrower terms? This analysis covered 1.296 terms, each with at least one narrower term in the ERIC thesaurus. It measured the postings per document of the entry terms and their narrower terms. There was almost no correlation between how often a term is assigned and how many similar looking narrower terms it has. Nevertheless, there were some sets of narrower terms that had much higher postings per document rates than their entry terms. Many of these narrower terms were much newer to the thesaurus than were their entry terms

  Atkins, T.V.; Ostrow, R. (Hrsg.): Cross-reference index : a guide to search terms.2nd ed.
  New York : Bowker, 1989.
  
  Abstract: The first edition of this work, published in 1974, was designed for librarians. It contained an alphabetical listing of subject headings in six widely used sourdes: LCSH, Sears List, Readers' Guide to Periodical Literature, New York Times Index, PAIS, and Business Periodical Index. It was a useful and popular tool, but the rapid growth of information has resulted in new access tools, both print and online, and new subject headings. The second edition of Cross-reference index reflects this expansion. The editors have added headings from the Thesaurus of ERIC Descriptors, the Thesaurus of of Psychological Index Terms, and the Subject Guide to IAC Databases to provide broader coverage of current affairs, social science, amd business. They have also redesigned the format to encourage use by the public as well as by professionals. The expansion has increased the number of main headings from 1.386 to 1.684, and the new format directs users up to 50 comparable or related terms rather than three. This creates easy access to 42.000 search terms. Cross-reference index is in two parts: an alphabetical index and a main entry section. Users consult the alphabetical section first. This refers them to one or more main-entry headings, which are in alphabetical order and numbered to correspond to the index. Under each main entry the related subject headings are arranged alphabetically in a chart format with eight columns, one for each source. An X in a colums shows that the particular source uses a given term. These charts are easy to use and make indexing quirks readily apparent. Under the entry Blood, for example, one can see that LC uses Blood-vessels, while Readers' Guide, Sears, and Psychinfo use Blood vessels. Under Broadcasting, Readers' Guide uses Television broadcasting--News, LC and IAC use Television broadcasting of news, while PAIS uses Television--news. Using this book will cut down on the frustration that often accompanies research. The diversity of the sources included will also provide several points of view, offerings users new approaches that they might not have considered. Cross-reference Index belongs in all reference collections that own most of the sources indexed.
