- 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
- Describes the variety of search services supporting library reference functions offered by the RLG in the USA. The best known of these is RLIN, the massive bibliographic database and related services originally developed for shared cataloguing. In the last few years RLG has added CitaDel, an online search system that provides access to indexing/abstracting databases; and Zephyr, a Z39.50 server that amkes the RLIN and CitaDel databases searchable through a library's online catalogue. RLG also offers document delivery connections, including Ariel and Internet based document delivery software, for a full complement of online reference support for academic and public libraries

- 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
- Examines why online systems and CD-ROMs are producing a greater need for bibliographic instruction. Most online systems and CD-ROMs operate with the same software developed for the first online systems 20 years ago. Innovative search techniques such as natural language have spread from inhouse databases to the commercial online and CD-ROM environment. Personal Librarian and Westlaw Is Natural represent the online second generation. Discusses Personal Librarian; CD-ROM products; online expansion and DIALOG and Personal Library Software

- Abstract
- This article presents part of phase 2 of a research project funded by the NSF-National Science Digital Library Project, which observed how academic users interact with the ScienceDirect information retrieval system for simulated class-related assignments. The ultimate goal of the project is twofold: (1) to find ways to improve science and engineering students' use of science e-journal systems; (2) to develop methods to measure user interaction behaviors. Process-tracing technique recorded participants' processes and interaction behaviors that are measurable; think-aloud protocol captured participants' affective and cognitive verbalizations; pre- and post-search questionnaires solicited demographic information, prior experience with the system, and comments. We explored possible relationships between affective feelings and cognitive behaviors. During search interactions both feelings and thoughts occurred frequently. Positive feelings were more common and were associated more often with thoughts about results. Negative feelings were associated more often with thoughts related to the system, search strategy, and task. Learning styles are also examined as a factor influencing behavior. Engineering graduate students with an assimilating learning style searched longer and paused less than those with a converging learning style. Further exploration of learning styles is suggested.

- 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

- 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

- Abstract
- Three questions - what can be studied; how can studies be done; and what can be measured - drive research methods and help to identify information metrics for user studies. User studies can investigate user needs, search strategies, or preferences. Observing and asking, the two main methods for conducting user studies, yield quantitative and qualitative data through studying patterns of behavior and insights into motivation. ciber (Centre for Information Behaviour and the Evaluation of Research, City University, London) is in a good position to continue supporting information user behavior studies that use a variety of methods to gather both qualitative and quantitative data and help establish consistent metrics.

- 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
- 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.

- Abstract
- The article presents the early findings of an exploratory deep log analysis of journal usage on OhioLINK, conducted as part of the MaxData project, funded by the U.S. Institute of Museum and Library Services. OhioLINK, the original Big Deal, provides a single digital platform of nearly 6,000 full-text journals for more than 600,000 people; for the purposes of the analysis, the raw logs were obtained from OhioLINK for the period June 2004 to December 2004. During this period approximately 1,215,000 items were viewed on campus in October 2004 and 1,894,000 items viewed off campus between June and December 2004. This article provides an analysis of the age of material that users consulted. From a methodological point of view OhioLINK offered an attractive platform to conduct age of publication usage studies because it is one of the oldest e-journal libraries and thus offered a relatively long archive and stable platform to conduct the studies. The project sought to determine whether the subject, the search approach adopted, and the type of journal item viewed (contents page, abstract, full-text article, etc.) was a factor in regard to the age of articles 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.
