    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
    The Functional Requirements for Bibliographic Records (FRBR) data model holds great potential for improving access to library resources, but may not affect all libraries in the same way. The Joint Steering Committee for Revision of AACR (Anglo-American Cataloguing Rules), assisted by the work of its Format Variation Working Group, is exploring ways to incorporate FRBR into the next edition of the Anglo-American Cataloguing Rules to facilitate collocation at the level of the FRBR entity expression. Several library system vendors are also adding FRBR-based functionality to their systems. A combination of these two approaches to FRBR can provide significant benefits to users. Most FRBR entities and attributes are already present in library catalog records, and the influence of FRBR can also be seen in existing library activities. FRBR is thus not something totally foreign, but a fresh, more rigorous way of thinking about what libraries already do that provides a basis for designing new ways to improve users' access to library resources.

    Abstract
    This study examines the effects of the search interface and Boolean logic training on user search performance and satisfaction. We compared the use of an assisted search tool to that of a simple search interface like those typically found at commercial search engine sites. We found that the assisted search tool had a significant positive effect on performance, satisfaction, and confidence. Promoting the use of advanced search features is therefore in the best interest of both Web search providers and users. In the absence of an assisted interface, a simple interface coupled with Boolean logic training was also an effective means for improving user performance. Given that most searchers choose to use the simple search box, it is important to provide them with applicable training to promote the effective use of the search tool. Interestingly, coupling the assisted interface with Boolean training was no more effective than either treatment alone.

    Abstract
    Many kinds of structure can be discerned in the headings and rules governing the Library of Congress Subject Headings. By addressing these structures at different levels, librarians can develop different approaches to the machine-assisted validation of subject headings, from the checking of individual words to the validation of complex forms of heading/subdivision compatibility. Using computer programs to assist with maintenance of subject headings is becoming increasingly necessary as technical services librarians strive to create consistent and useful patterns of subject collocation in library catalogs

    Abstract
    This article reports research an analyzing and visualizing the impact of governmental funding an the amount and citation counts of research publications. For the first time, grant and publication data appear interlinked in one map. We start with an overview of related work and a discussion of available techniques. A concrete example- grant and publication data from Behavioral and Social Science Research, one of four extramural research programs at the National Institute an Aging (NIA)-is analyzed and visualized using the Vxlnsight® visualization tool. The analysis also illustrates current existing problems related to the quality and existence of data, data analysis, and processing. The article concludes with a list of recommendations an how to improve the quality of grant-publication maps and a discussion of research challenges for indicator-assisted evaluation and funding of research.

    Abstract
    Given that time is money, Web searching can be a very expensive proposition. Even with the best search technology, the usefulness of search results depends on the searcher's ability to use that technology effectively. In an effort to improve this ability, our research investigates the effects of logic training, interface training, and the type of search interface on the search process. In a study with 145 participants, we found that even limited training in basic Boolean logic improved performance with a simple search interface. Surprisingly, for users of an interface that assisted them in forming syntactically correct Boolean queries, performance was negatively affected by logic training and unaffected by interface training. Use of the assisted interface itself, however, resulted in strong improvements in performance over use of the simple interface. In addition to being useful for search engine providers, these findings are important for all companies that rely heavily on search for critical aspects of their operations, in that they demonstrate simple means by which the search experience can be improved for their employees and customers.

    Abstract
    Interactive Cross-Language Information Retrieval (CLIR), a process in which searcher and system collaborate to find documents that satisfy an information need regardless of the language in which those documents are written, calls for designs in which synergies between searcher and system can be leveraged so that the strengths of one can cover weaknesses of the other. This paper describes an approach that employs user-assisted query translation to help searchers better understand the system's operation. Supporting interaction and interface designs are introduced, and results from three user studies are presented. The results indicate that experienced searchers presented with this new system evolve new search strategies that make effective use of the new capabilities, that they achieve retrieval effectiveness comparable to results obtained using fully automatic techniques, and that reported satisfaction with support for cross-language searching increased. The paper concludes with a description of a freely available interactive CLIR system that incorporates lessons learned from this research.

    Abstract
    The Data Documentation Initiative (DDI) is an international effort to establish an XML-based standard for the compilation, presentation, and exchange of documentation for datasets in the social and behavioral sciences. The most recent version 3.0 of the DDI supports a rich and structured set of metadata elements that not only fully informs a potential data analyst about a given dataset but also facilitates computer processing of the data. Moreover, data producers will find that by adopting the DDI standard they can produce better and more complete documentation as a natural step in designing and fielding computer-assisted interviewing. DDI 3.0 embraces the full life cycle of the data from conception, through development of the data collection instrument, collection and cleaning of data, production of data products, distribution, preservation, and reuse or analysis of the data. DDI 3.0 is designed to facilitate sharing schemes for concepts, questions, coding, and variables within organizations or throughout the social science research community. Comparison through direct inheritance as in the case of comparisonby- design or through the mapping of items like variables or categories allow capture of the harmonization processes used in creating integrated files in an uniform and machine-actionable way. DDI 3.0 is providing the structural support needed to facilitate comparative survey work in a way that was previously unavailable in an open, non-proprietary system. A specific DDI module allows for the capture and expression of native Dublin Core elements (DCMES), used either as references or as descriptions of a particular set of metadata. This module uses the simple Dublin Core namespace represented as XML Schema following the guidelines for implementing Dublin Core in XML. In DDI, the Dublin Core is not used as the primary citation mechanism - this module is included to support applications which understand the Dublin Core XML, but which do not understand DDI. This module is used wherever citations are permitted within DDI 3.0 (like citations of a study description or of other material). DDI 3.0 is aligned with other metadata standards as well: with SDMX (time-series data) for exchanging aggregate data, with ISO/IEC 11179 (metadata registry) for building data registries such as question, variable, and concept banks, and with FGDC and ISO 19115 (geographic standards) for supporting GIS users. DDI 3.0 is described in a conceptual model which is also expressed in the Universal Modeling Language (UML). Modular XML Schemas are derived from the conceptual model. Many elements support computer processing - that is, it will go beyond being "human readable", and move toward the goal of being "machine-actionable". The final release of DDI 3.0 has been published on April 28th 2008. The standard was developed by the DDI Alliance, an international group encompassing data archives and research institutions from several countries in Western Europe and North America. Earlier versions of DDI provide examples of institutions and applications: the Inter-university Consortium for Political and Social Research (ICPSR) Data Catalog, the Council of European Social Science Data Services (CESSDA) Data Portal, the Dataverse Network, the International Household Survey Network (IHSN), NESSTAR Software for publishing data on the Web and online analysis, and the Microdata Management Toolkit (by the World Bank Data Group for IHSN).

    Abstract
    Papers on the cataloging of electronic resources have focused on electronic journals and Internet resources such as Web sites and not on electronic books. Electronic books are nonserial monographic resources accessed with a computer either directly or remotely. Rules and standards for cataloging electronic resources have changed and continue to change. This article discusses the electronic book as a unique manifestation and provides practical instruction on the application of current cataloging rules. The cataloging elements covered are control fields and variable data fields, including classification, uniform titles, title information, edition information, type and extent of the resource, publication and distribution information, physical description, series statements, notes, and subject analysis.

    Abstract
    This paper presents a detailed analysis of the structure and components of queries written by experimental participants in a study that manipulated two factors found to affect end-user information retrieval performance: training in Boolean logic and the type of search interface. As reported previously, we found that both Boolean training and the use of an assisted interface improved the participants' ability to find correct responses to information requests. Here, we examine the impact of these training and interface manipulations on the Boolean operators and search terms that comprise the submitted queries. Our analysis shows that both Boolean training and the use of an assisted interface improved the participants' ability to correctly utilize various operators. An unexpected finding is that this training also had a positive impact on term selection. The terms and, to a lesser extent, the operators comprising a query were important factors affecting the participants' performance in query tasks. Our findings demonstrate that even small training interventions can improve the users' search performance and highlight the need for additional information retrieval research into how search interfaces can provide superior support to today's untrained users of the Web.
