    Abstract
    Examines statistically the public's use and attitudes towards interactive and personal health services via an online questionnaire survey and enhances these data with an expert assessment of a number of consumer health sites and their services. Over a period of three weeks more than 1,300 people responded to an online questionnaire produced by The British Life and Internet Project. Of the respondents, 81 per cent were British. The likely potential uptake figure for support group participation among Internet health users is about 20 per cent while around 11 to 13 per cent will go online to describe a medical condition. Those in poor heath were approximately ten to 13 times more likely to have participated in an online support group. Those aged over 65 were four times as likely to e-mail their doctor. More positive health outcomes were associated with those respondents that participated in online support groups and the least number of health outcomes were associated with those people that maintained e-mail contact with a doctor or surgery.

    Abstract
    Where Internet users go, attackers follow. Users embrace e-mail; then spammers fill their inboxes with junk mail. With the rise in online commerce, phishers trick them into giving up their passwords. Users find handy downloadable applications; adware vendors bundle them with pop-up-spewing add-ons. The rise of Internet search brings a new type of risk. Hostile Web sites might seek to harm users or take advantage of them - whether through spyware, spam, scams, or other bad practices - because search engines often do not filter these sites from their results. Consider this scenario: Suzy wants to perform Beyonce's Crazy in Love for her school talent show. To make sure she dresses the part, she performs a Google search for >celebrity photos<. When she clicks the first search result, celebritypictures.duble.com, she is quickly prompted to install an adware-bundled ActiveX control in order to browse the site's contents. Eager to view photos of her celebrity role model, she accepts the installation of a new browser toolbar and a pop-up serving adware program. In principle, search engines' listing rules, ranking rules, and advertising policies might shield users from some bad practices, and users' good judgment could protect them from others. But empirically, search engines often lead users to dangerous content. My analysis of search engine safety finds bad practices among approximately 5% of search results for popular keywords, or roughly one site per page of search results.

    Abstract
    Purpose - The purpose of this paper is to show how an academic library added access points to its digital reference service outside its traditional library web pages (e.g. online catalog, subscription databases). It seeks to determine whether, how, and to what extent these access points were used by patrons. Design/methodology/approach - Almost 1,200 chat, e-mail, and instant message digital reference transactions were examined. The data collected included: status of user; format by which questions were submitted (chat, e-mail, IM); subject area of the question; type of question, and the access point from which the patron submitted the question. The data were analyzed using SPSS statistical software. Findings - Patrons used the access points in external resources over 25 per cent of the time. They took advantage of the access points as their research needs arose. An increase in the amount of reference transactions received was observed after the addition of the external access points. Practical implications - This study may be useful in planning, administering, and staffing digital reference services. Originality/value - This is currently the only comprehensive study that has examined digital reference transactions in multiple formats, the correlation between access point and information need, and the impact of adding access points to digital reference in external resources.

    Abstract
    Purpose - In a 31-month period, 1,184 questions addressed to the Internet Public Library's (IPL) reference service remained unanswered on the grounds that they were "out of scope". This paper aims to analyze the questions as artifacts of users' expectations to better chart the distinction between user and librarian views of reference service. Design/methodology/approach - Each question is examined to identify two user expectations, i.e. what kinds of information librarians could provide and what kinds of needs librarians could help meet. Emergent coding with a code-recode rate of 97 per cent identifies 23 types of expected librarian assistance and 28 characteristics of expected applications of that assistance. Findings - Users expect IPL librarians to provide personal advice, analysis, facts, procedures, instruction, technology guidance and evaluation. IPL librarians are expected to help users in making decisions, solving problems, completing processes and developing understanding. Research limitations/implications - Limitations include the use of a single coder and the use of single institution's data set. Mapping these user expectations suggests a need for librarians to consider further development of reference service in terms of its judgment, form, and involvement parameters. Practical implications - Reference service policies and training should be examined to enhance librarians' abilities to consider judgment, form, and involvement parameters primarily from the user's perspective. Originality/value - This paper analyzes that which is rarely seen, i.e. e-mail reference questions which are considered beyond the scope of service. Additionally, the IPL question pool provides a broader range of user mental models than would be found in any geographically bound institution.

    Abstract
    It has become increasingly common for libraries to provide a reference service which operates via e-mail or through online forms. This paper compares the performance of three digital reference services available on the World Wide Web, namely, AllExperts, Ask a Librarian, and Internet Public Library (a fourth service, Ask Bob, was included initially but eventually excluded). The online digital reference/"expert" services are generally very effective; most provide an answer within three days, and include suggestions for sources of further information. Although the general response rate from all the services was good, library-based services were found to be more trustworthy since they provided the answers together with the sources.

    Abstract
    Automatic text classification (ATC) is a discipline at the crossroads of information retrieval (IR), machine learning (ML), and computational linguistics (CL), and consists in the realization of text classifiers, i.e. software systems capable of assigning texts to one or more categories, or classes, from a predefined set. Applications range from the automated indexing of scientific articles, to e-mail routing, spam filtering, authorship attribution, and automated survey coding. This article will focus on the ML approach to ATC, whereby a software system (called the learner) automatically builds a classifier for the categories of interest by generalizing from a "training" set of pre-classified texts.

    Abstract
    It is taken for granted that the Dewey Decimal Classification and Library of Congress Classification are the most used classification systems worldwide. However, LIS literature does not include studies or research reports about classification systems currently used in Latin American libraries, and the reasons behind their adoption. This paper shows the results of an e-mail survey carried out among Latin American libraries to learn what were the classifications systems used in them, as well as some of the reasons that motivated them to select those classification systems.

    Abstract
    With the proliferation of new information channels such as the Web, e-mail and wireless, it is becoming increasingly important to understand the impact of these technologies within information-seeking and retrieval contexts. This issue of Aslib Proceedings presents research that begins to address the notion of "information disparity". It aims to weave a common thread between the challenges of reconciling disparate information needs in an environment complicated by fragmented or disparate data sources. This article lists several emerging trends that should begin to challenge traditional notions of our research field.

    Abstract
    With domestic violence directly impacting over 5 million victims in the United States annually, the growing e-health and e-government networks are developing digitally based resources for both victims and those who aid them. The well-established community information and referral role of public libraries dovetails with this digital referral network model; however, no study of the actual service provided by public libraries is available. This examination of e-mail reference responses to requests for safe-house contact information revealed major gaps in cyber-safety awareness and uneven implementation of professional standards for virtual reference service. Implications for information system design, professional standards, education, and future research are discussed.

    Abstract
    This study revisits managers who were first interviewed more than 10 years ago to identify their personal information management (PIM) behaviors. The purpose of this study was to see how advances in technology and access to the Web may have affected their PIM behaviors. PIM behaviors seem to have changed little over time, suggesting that technological advances are less important in determining how individuals organize and use information than are the tasks that they perform. Managers identified increased volume of e-mail and the frustration with having to access multiple systems with different, unsynchronized passwords as their greatest PIM challenges. Organizational implications are discussed.

    Abstract
    Purpose - The purpose of this paper is to focus on duplicate record detection algorithms used for detection in bibliographic databases. Design/methodology/approach - Individual algorithms, their application process for duplicate detection and their results are described based on available literature (published articles), information found at various library web sites and follow-up e-mail communications. Findings - Algorithms are categorized according to their application as a process of a single step or two consecutive steps. The results of deletion, merging, and temporary and virtual consolidation of duplicate records are studied. Originality/value - The paper presents an overview of the duplication detection algorithms and an up-to-date state of their application in different library systems.

    Rez. in BuB 56(2004) H.3: "Auskunfts- und Informationsdienst wird in den USA als unverzichtbare und wohl wichtigste bibliothekarische Tätigkeit betrachtet. Daher verwundert nicht, dass die Popularisierung des Internet Bibliothekare und Bibliotheken frühzeitig dazu veranlasst hat, ihre Auskunftsdienstleistungen im Web anzubieten. Dies geschah zunächst durch organisierte Auskunft per E-Mail, später per Webformular und vor allem seit 2000/2001 verstärkt per Chat. Als zusammenfassende Bezeichnung für diese Varianten wird meist der Begriff digital reference verwendet. In den USA, aber auch in Australien, Großbritannien oder Skandinavien schenkt man dem Thema Digital Reference schon seit mehreren Jahren größte Aufmerksamkeit. Die Zahl der bislang dazu publizierten Fachaufsätze lag Ende 2003 bereits weit über 600, jährlich im November findet seit 1999 die »Digital Reference Conference« statt, und mit DIG_REF sowie LiveReference existieren zwei Diskussionslisten, die sich ausschließlich mit Fragen bibliothekarischer Auskunft im Internet beschäftigen. Im vergangenen Jahr sind in den USA allein vier umfangreiche Monographien zu Digital Reference erschienen, darunter das hier zu besprechende Werk von Anne Lipow. ... Gegenwärtig deutet sich an, dass das Thema Digital Reference, Online-Auskunft oder Auskunft per Chat in deutschen Bibliotheken auf mehr Interesse stößt als in den vergangenen Jahren. Nachdem bislang vorwiegend (einige wenige) wissenschaftliche Bibliotheken ChatAuskunft anbieten, haben mehrere Öffentliche Bibliotheken, darunter die ZLB Berlin und die Stadtbücherei Frankfurt am Main, angekündigt, zukünftig auchAuskunftperChatanbieten zu wollen. Eine wichtige Rolle spielt in diesem Zusammenhang der weltweite Auskunftsverbund QuestionPoint, der von OCLC gemeinsam mit der Library of Congress betrieben wird. Sowohl denjenigen, die sich noch im Unklaren sind, als auch jenen, die entsprechende Planungen bereits beschlossen haben, kann der Band von Anne Lipow nur wärmstens empfohlen werden." (H. Rösch)
