    Abstract
    This review describes experimental designs (users, search tasks, measures, etc.) used by 31 controlled user studies of information visualization (IV) tools for textual information retrieval (IR) and a meta-analysis of the reported statistical effects. Comparable experimental designs allow research designers to compare their results with other reports, and support the development of experimentally verified design guidelines concerning which IV techniques are better suited to which types of IR tasks. The studies generally use a within-subject design with 15 or more undergraduate students performing browsing to known-item tasks on sets of at least 1,000 full-text articles or Web pages on topics of general interest/news. Results of the meta-analysis (N = 8) showed no significant effects of the IV tool as compared with a text-only equivalent, but the set shows great variability suggesting an inadequate basis of comparison. Experimental design recommendations are provided which would support comparison of existing IV tools for IR usability testing.

    Abstract
    Library vendors' use of Unicode is leading to library systems with multiscript capability, which offers the prospect of multiscript authority records. Although librarians tend to focus on Unicode in relation to non-Roman scripts, language is a more important feature of authority records than script. The concept of a catalog locale (of which language is one aspect) is introduced. Restrictions on the structure and content of a MARC 21 authority record are outlined, and the alternative structures for authority records containing languages written in non-Roman scripts are described.

    Abstract
    A survey of 261 libraries was undertaken to determine the level of use of and duties performed by student assistants in monographic cataloging operations. Ninety-five of 142 responding libraries (64.1 percent) indicate that they use student assistants for some type of monographic cataloging tasks. These tasks are downloading of bibliographic and authority records, monographic cataloging, classification, subject heading authority control, holdings, database maintenance, and editing of 246 or 505 MARC tags. Some respondents expressed reluctance to use student assistants for higher-level cataloging tasks.

    Abstract
    Evaluative and comparative studies of catalog data have tended to focus on methods that are labor intensive, demand expertise, and can examine only a limited number of records. This study explores an alternative approach to gathering and analyzing catalog data, focusing on the currency and consistency of controlled headings. The resulting data provide insight into libraries' use of changed headings and their success in maintaining currency and consistency, and the systems needed to support the current pace of heading changes.

    Abstract
    This study is an examination of the overlap between author-assigned keywords and cataloger-assigned Library of Congress Subject Headings (LCSH) for a set of electronic theses and dissertations in Ohio State University's online catalog. The project is intended to contribute to the literature on the issue of keywords versus controlled vocabularies in the use of online catalogs and databases. Findings support previous studies' conclusions that both keywords and controlled vocabularies complement one another. Further, even in the presence of bibliographic record enhancements, such as abstracts or summaries, keywords and subject headings provided a significant number of unique terms that could affect the success of keyword searches. Implications for the maintenance of controlled vocabularies such as LCSH also are discussed in light of the patterns of matches and nonmatches found between the keywords and their corresponding subject headings.

    Abstract
    Cornell University Library (CUL) has developed a largely automated method for providing title-level catalog access to electronic journals made available through aggregator packages. CUL's technique for automated e-journal record creation and maintenance relies largely on the conversion of externally supplied metadata into streamlined, abbreviated-level MARC records. Unlike the Cooperative Online Serials Cataloging Program's recently implemented aggregator-neutral approach to e-journal cataloging, CUL's method involves the creation of a separate bibliographic record for each version of an e-journal title in order to facilitate automated record maintenance. An indexed local field indicates the aggregation to which each title belongs and enables machine manipulation of all the records associated with a specific aggregation. Information encoded in another locally defined field facilitates the identification of all of the library's e-journal titles and allows for the automatic generation of a Web-based title list of e-journals. CUL's approach to providing title-level catalog access to its e-journal aggregations involves a number of tradeoffs in which some elements of traditional bibliographic description (such as subject headings and linking fields) are sacrificed in the interest of timeliness and affordability. URLs (Uniform Resource Locators) and holdings information are updated on a regular basis by use of automated methods that save on staff costs.

    Abstract
    Patron queries at a four-year comprehensive college's online public access catalog were examined via transaction logs from March 2007. Three representative days were isolated for a more detailed examination of search characteristics. The results show that library users employed an average of one to three terms in a search, did not use Boolean operators, and made use of limits one-tenth of the time. Failed queries remained problematic, as a full one-third of searches resulted in zero hits. Implications and recommendations for improvements in the online public access catalog are discussed.

    Abstract
    In 2004, the ALCTS (Association for Library Collections & Technical Services) Cataloging and Classification Section Subject Analysis Committee (SAC) produced the report Recommendations for Providing Access to, Display of, Navigation within and among, and Modifications of Existing Practice Regarding Subject Reference Structures in Automated Systems. This document is one important outcome of nearly ten years' work by three SAC (Subject Analysis Committee) subcommittees investigating the theoretical, pragmatic, and political dimensions of improving subject access through better use of reference structure data. The work of those subcommittees is reviewed and their recommendations are described and summarized. Potential future effects of the report are discussed, as is a snapshot view of several major automation systems' current compliance with the recommendations.

    Abstract
    The Core Standard for Rare Books, known as the DCRB Core standard, was approved by the Program for Cooperative Cataloging for use beginning in January 1999. Comparable to the core standards for other types of materials, the DCRB Core standard provides requirements for an intermediate level of bibliographic description for the cataloging of rare books. While the Core Standard for Books seems to have found a place in general cataloging practice, the DCRB Core standard appears to have met with resistance among rare book cataloging practitioners. This study investigates the extent to which such resistance exists by examining all of the DCRB Core records in the OCLC (Online Computer Library Center) Online Union Catalog (WorldCat) and the Research Libraries Croup Union Catalog (RLIN) databases that were created during the standard's first five years. The study analyzes the content of the records for adherence to the standard and investigates the ways in which the flexibility of the standard and cataloger's judgment augmented many records with more than the mandatory elements of description and access.

    Abstract
    Reclassification was a popular trend during the 1960s and 1970s for many academic libraries wanting to change from Dewey Decimal Classification (DDC) to Library of Congress (LC) Classification. In 2002, Southern Illinois University at Carbondale's Morris Library changed from DDC to LC. If one academic library recently converted, might other DDC academic libraries consider switching, too? Conversely, for those academic libraries that remain with DDC, what are the reasons they continue with it? A survey of thirty-four DDC academic libraries in the United States and Canada determined what factors influence these libraries to continue using DDC, and if reclassification is something they have considered or are considering. The survey also investigated whether patrons of these DDC libraries prefer LC and if their preference influences the library's decision to reclassify. Results from the survey indicate that the issue of reclassification is being considered by some of these libraries even though, overall, they are satisfied with DDC. The study was unable to determine if patrons' preference for a classification scheme influenced a library's decision to reclassify.

    Abstract
    The virtual university environment provides librarians with new opportunities to contribute to the educational process. Building on the success of team-teaching a traditional liberal arts core course with composition and communications faculty, librarians and a communications professor worked together to integrate the Association of College & Research Libraries (ACRL) Information Literacy Competency Standards for Higher Education (2000) into the online environment. The resulting graduate-level course in multimedia literacy assembled faculty and curriculum resources normally untapped in traditional classrooms. All five information literacy standards covering need, access, evaluation, use and the social, economic, legal, and ethical issues surrounding information use were addressed. Readings and threaded discussions about intellectual property, fair use of copyrighted materials, the evaluation of free and fee-based Web information and Web page design and construction prepared students to work in groups to design and construct Web sites. Students also completed a capstone project in the form of individual Web portfolios, which demonstrated the information and multimedia principles they learned in the class. Assessment of information literacy skills occurred through the analysis of student discussion, evaluative annotations, Web site assignments, perception surveys, and a master's level comprehensive exam question. What was learned in this course will serve as a model for future collaborative partnerships in which faculty and librarians work together to ensure that students who learn from a distance truly master information literacy competencies.

    Abstract
    This article seeks to address the following questions: Why do certain people, who are fully information literate with printed materials, become hesitant and even reluctant when it comes to finding something on the Internet? And why do we, information professionals, find it difficult to support them adequately? Mature users of digital information are often skeptical about the value of the Internet as a source for professional information. Over the years much has been achieved, but many prophecies of the experts on digitalization from the early hours still have not yet been fulfilled. Mature users do possess all skills needed to be digital-information literate, but they need to be assisted in specific areas where those skills are insufficient. They tend to blame themselves even if shortcomings in accessibility of digital sources and computer errors obstruct their search. Operating hardware requires a dexterity that can only be acquired by experience. Instruction should be hands-on; demonstration is far less effective. Special attention should be given to reading and interpreting navigation information on the screen and to the search strategies the Internet requires. Use of imagination and trial-and-error methods are to be recommended in this respect.

    Abstract
    This review of 2004 and 2005 serials literature covers the themes of cost, management, and access. Interwoven through the serials literature of these two years are the importance of collaboration, communication, and linkages between scholars, publishers, subscription agents and other intermediaries, and librarians. The emphasis in the literature is on electronic serials and their impact on publishing, libraries, and vendors. In response to the crisis of escalating journal prices and libraries' dissatisfaction with the Big Deal licensing agreements, Open Access journals and publishing models were promoted. Libraries subscribed to or licensed increasing numbers of electronic serials. As a result, libraries sought ways to better manage licensing and subscription data (not handled by traditional integrated library systems) by implementing electronic resources management systems. In order to provide users with better, faster, and more current information on and access to electronic serials, libraries implemented tools and services to provide A-Z title lists, title by title coverage data, MARC records, and OpenURL link resolvers.

    Abstract
    Authority control has long been an important part of the cataloging process. However, few studies have been conducted examining how librarians learn about it. Research conducted to date suggests that many librarians learn about authority control on the job rather than in formal classes. To offer an introduction to authority control information for librarians, an annotated bibliography is provided. It includes monographs, articles and papers, electronic discussion groups, Web sites related to professional conferences, additional Web sites related to authority control, and training offered through the Name Authority Cooperative Program and the Subject Authority Cooperative Program. A summary of possible future trends in authority control is also provided.

    Abstract
    This paper presents results from a fall 2003 survey of heads of cataloging at Association of Research Libraries United States academic libraries. The survey focused on the current number of professional catalogers and their responsibilities as well as future projections for demand for catalogers and thoughts about their roles. The study found that the numbers of professional catalogers are remaining constant or decreasing, and approximately one-third are projected to retire in the next decade. In addition, the role of the professional cataloger is perceived as continuing to evolve toward more cataloging-related activities and management and less direct cataloging. Most respondents predicted the professional cataloger has a role in the future and felt prepared for that future. Some respondents suggested that metadata cataloging would be a growing role in that future. This paper concludes with additional questions about the future of professional catalogers and cataloging.

    Abstract
    This paper examines existing library and personnel literature to determine whether any strides have been made among academic libraries in determining cataloging productivity benchmarks. The perceived importance of performance evaluations based on quantitative and qualitative standards is explored, as is the intended effect of established cataloging production norms. The pros and cons of cataloging benchmarks are analyzed from four different perspectives: library administration, library human resources, cataloging managers, and cataloging staff. The paper concludes that additional research is needed in order to determine whether established production cataloging benchmarks are feasible and meaningful within academic libraries.

    Abstract
    Some members of the library community, including the Library of Congress Working Group on the Future of Bibliographic Control, have suggested that libraries should open up their catalogs to allow users to add descriptive tags to the bibliographic data in catalog records. The web site LibraryThing currently permits its members to add such user tags to its records for books and therefore provides a useful resource to contrast with library bibliographic records. A comparison between the LibraryThing tags for a group of books and the library-supplied subject headings for the same books shows that users and catalogers approach these descriptors very differently. Because of these differences, user tags can enhance subject access to library materials, but they cannot entirely replace controlled vocabularies such as the Library of Congress subject headings.
