    Abstract
    Outlines 3 generations of online searching: to 1981, when personal computers became ubiquitous, when searching was done from dumb terminals by intermediaries; from 1982 to 1991, when through the use of the PC, faster transmission speeds and the advent of ASCII full text, specialized end users joined intermediaries in the exploitation of online; and a generation characterized by multimedia PCs, higher transmission speeds, ASCII and 'image' full text databases, the invlovement of the general end user. Reviews the evolution of these 3 generations in 4 specific areas: content/databases; people and organizations involved; the places people search; motives for using online; and search engines and interfaces used

    Abstract
    This article reports the results of a study into the use of discrete journal-article components, particularly tables and figures extracted from published scientific journal articles, and their application to teaching and research. Sixty participants were introduced to and asked to perform searches in a journal-article component prototype that presents individual tables and figures as the items returned in the search results set. Multiple methods, including questionnaires, observations, and structured diaries, were used to collect data. The results are analyzed in the context of previous studies on the use of scientific journal articles and in terms of research on scientists' use of specific journal-article components to find information, assess its relevance, read, interpret, and disaggregate the information found, and reaggregate components into new forms of information. Results indicate that scientists believe searching for journal-article components has value in terms of (a) higher precision result sets, (b) better match between the granularity of the prototype's index and the granularity of the information sought for particular tasks, and (c) fit between journal-article component searching and the established teaching and research practices of scientists.

    Abstract
    An international survey of over 3,600 researchers examined how trustworthiness and quality are determined for making decisions on scholarly reading, citing, and publishing and how scholars perceive changes in trust with new forms of scholarly communication. Although differences in determining trustworthiness and authority of scholarly resources exist among age groups and fields of study, traditional methods and criteria remain important across the board. Peer review is considered the most important factor for determining the quality and trustworthiness of research. Researchers continue to read abstracts, check content for sound arguments and credible data, and rely on journal rankings when deciding whether to trust scholarly resources in reading, citing, or publishing. Social media outlets and open access publications are still often not trusted, although many researchers believe that open access has positive implications for research, especially if the open access journals are peer reviewed.

    Abstract
    In 1973 F. W. Lancaster published the first textbook about online information retrieval (with E. G. Fayen). That text and his later writings and books on the topics relating to online searching set the precedent for many books to follow. His early work also advocated many changes to the state-of-the-art systems and anticipated many of the characteristics of modern online information retrieval systems. Although the basic underlying structure of modern systems is still similar to what Lancaster wrote about thirty years ago, many of the changes he advocated have occurred. From an era of bibliographic databases on command-driven systems searched by library professionals, online systems have evolved to have friendlier interfaces, include full texts or links to full texts, and are targeted to the end users of the information. The information industry has evolved, as have the online search systems and tools that are so commonplace today.

    Novice end users were given 2 hours of training in searching a full-text magazine database (Magazine ASAP(TM)) on DIALOG. Subjects searched during 3 to 4 sessions in the presence of a trained monitor who prompted them to think aloud throughout the sessions. qualitative analysis of the transcripts and transaction logs yielded empirical information on user variables (purpose, motivation, satisfaction), uses of the database, move types, and every question users asked during the searches. The spontaneous, naturalistic questions were categorized according to affective, cognitive, and sensorimotor speech acts. Results show that most of the searches were performed for the self and were work related. The most common use of the database was to retrieve full-text articles online and to download and print them out rather than read them on screen. The majority of searches were judged satisfactory. Innovative uses included browsing for background information and obtaining contextualized sentences for language teaching. Searchers made twice as many moves to limit sets as moves to expand sets. Affective questions outnumbered cognitive and sensorimotor questions by two to one. This preponderance of affective micro-information needs during searching might be addressed by new system functions

    Abstract
    Purpose - This article is an edited version of a report commissioned by the British Library and JISC to identify how the specialist researchers of the future (those born after 1993) are likely to access and interact with digital resources in five to ten years' time. The purpose is to investigate the impact of digital transition on the information behaviour of the Google Generation and to guide library and information services to anticipate and react to any new or emerging behaviours in the most effective way. Design/methodology/approach - The study was virtually longitudinal and is based on a number of extensive reviews of related literature, survey data mining and a deep log analysis of a British Library and a JISC web site intended for younger people. Findings - The study shows that much of the impact of ICTs on the young has been overestimated. The study claims that although young people demonstrate an apparent ease and familiarity with computers, they rely heavily on search engines, view rather than read and do not possess the critical and analytical skills to assess the information that they find on the web. Originality/value - The paper reports on a study that overturns the common assumption that the "Google generation" is the most web-literate.

    Abstract
    Online offers the advantage over CD-ROM and locally loaded databases of being able to search several databases simultaneously. However, even when different databases have common fields, they may be named differently. This is improving, particularly throught he efforts of Mead Data Central and DIALOG. Discusses searching single databases; 2 ways in which online systems standardise fields; the lack of standardisation in the field tag SF=; Dialog's standardisation; generic field designs; standardisation of field content and NEXIS and uniform segmentation

    Abstract
    As end users perform their own searches, more insight into their searching behaviour is needed. Identifies and describes the strategies, assessments and affective behaviours from the transcripts and keystroke records collected during 3 searches. The affective behaviours exhibited by the searchers show the involvement of other than cognitive activities in this intellectual pursuit. Particularly interesting is the single mindedness of the search strategies. Describes the searchers' online assessments of the usefulness of retrieved records including assessment strategies that were developed

    Considers some of the human factors in online interaction and Internet use. Discusses the following: users' need for help from libraries and librarians, given the difficulties people continue to have in accessing and using networked information; the challenge of user demands for speedy delivery of information and documents; the trend towards 'humanizing the net' through chat rooms and social agent interfaces (such as Microsoft's Bob); and the problems for libraries of users using the Internet for trivial or pornographic purposes

    Abstract
    Discusses the familiar problem of users are now confronted with the needs to impose order on myriad sources of information and to present them in an integrated way to users. Describes an attempt to provide such integration in the engineering field, Engineering Information Village, or Ei Village, produced by Engineering Information Inc. It resembles a WWW site, and integrates a traditional online abstracting and indexing service with access to WWW sites in the engineering field, contacts to engineering consultants, and access to other sources of interest to engineers. Explains how the metaphor of the village is carried though in the service and stresses the vetting process which seeks to guarantee that sources provided are authoritative. Also details the pricing of the service

    Abstract
    Increased reliance on electronic resources requires examination of the roles of librarians in several key ways. This paper addresses the need for further research into three important areas of electronic publishing. How is the change to digital information sources affecting the scholarly work of college and university students? Previous research shows that students rely on Web and online resources and ask for less help from librarians. We do not know, however, how these changes will affect the learning and scholarly work of college and university students. Research is also needed to determine how the differences between separate article and full journal databases affect the way research is done. What are the implications for scholarship of decisions being made about what publishers publish and what librarians purchase? Finally, are librarians--as intermediaries to the search process--still necessary in a digital age? Online systems are designed to be used independently but that may not always yield the best results.

    Abstract
    This paper examines how scientists working in government agencies in the U.S. are reacting to the "ethos of sharing" government-generated data. For scientists to leverage the value of existing government data sets, critical data sets must be identified and made as widely available as possible. However, government data sets can only be leveraged when policy makers first assess the value of data, in much the same way they decide the value of grants for research outside government. We argue that legislators should also remove structural barriers to interoperability by funding technical infrastructure according to issue clusters rather than administrative programs. As developers attempt to make government data more accessible through portals, they should consider a range of other nontechnical constraints attached to the data. We find that agencies react to the large number of constraints by mostly posting their data on their own websites only rather than in data portals that can facilitate sharing. Despite the nontechnical constraints, we find that scientists working in government agencies exercise some autonomy in data decisions, such as data documentation, which determine whether or not the data can be widely shared. Fortunately, scientists indicate a willingness to share the data they collect or maintain. However, we argue further that a complete measure of access should also consider the normative decisions to collect (or not) particular data.

    Abstract
    The study investigated the factors of response time, coverage, content and cost in CD-ROM and online versions of 2 popular databases: SilverPlatter Information Ins.'s and DIALOG's version of Psychological Abstracts (PsycINFO and PsycLIT) and Sociological Abstracts (Sociofile and Sociological Abstracts). Results confirm that, though the databases may be similar, significant differences do exist. Specifically, online searching gives a more consistent or predictable response time and yields greater currency, consistency and coverage

    Abstract
    Discusses the advent of software packages (termed front end packages) which are installed on PCs or Macintosh machines and provide the user with an interface to online databases. The packages involved usually provide graphical user interfaces (GUIs) and are dedicated to particular online systems. Focuses on KR ProBase which was introduced by Knight-Ridder in 1995 for information specialists to search DIALOG and DataStar (though not yet with a single interface). Describes the features of this product. Concludes with a brief discussion of the alternatives to host specific software packagaes, Z39.50 and Web browsers such as Netscape
