    Abstract
    The nature and implications of electrocopying are summarised. After a brief review of the principles of copyright, the issue of whether electrocopying infringes copyright is debated. Publishers are aware of the threat that electrocopying poses to their business. The various options available to publishers for responding to electrocopying are summarised. Patterns of scholarly communications and the relationships between authors, publishers and libraries are being challenged. Constructive dialogue is necessary if the issues are to be resolved

    Abstract
    A review of recent developments in electronic publishing, with a focus on Open Access (OA) is provided. It describes the two main types of OA, i.e. the `gold' OA journal route and the 'green' repository route, highlighting the advantages and disadvantages of the two, and the reactions of the publishing industry to these developments. Quality, cost and copyright issues are explored, as well as some of the business models of OA. It is noted that whilst so far there is no evidence that a shift to OA will lead to libraries cancelling subscriptions to toll-access journals, this may happen in the future, and that despite the apparently compelling reasons for authors to move to OA, so far few have shown themselves willing to do so. Conclusions about the future of scholarly publications are drawn.

    Abstract
    The rapidly increasing volume and variety of electronic or digitized information sources and their accessibility worldwide, have brought to the surface new issues concerning intellectual property, the complexity of the related legal questions and application of legislative measures in real world situations. Attemps to define 'intellectual property' from different points of view; considers the different types with different 'strengths' of protection, and the underlying objectives of such protection. Discusses copyright and international treaties on intellectual property, what is protected and for how long, the concept of fair use and the role of organizations concerned with reproduction rights. Presents a brief overview of the intellectual property questions relating to electronic media: machine readable databases, the information resources on the Internet, and images; electrocopying and downloading of texts and images from networks; and the special nature and copyright problems of multimedia. Also considers moral rights and the need for and feasibility of establishing Electronic Copyright Management System (ECMS)

    Abstract
    Purpose - This review aims to show, broadly, how the h-index has become a subject of widespread debate, how it has spawned many variants and diverse applications since first introduced in 2005 and some of the issues in its use. Design/methodology/approach - The review drew on a range of material published in 1990 or so sources published since 2005. From these sources, a number of themes were identified and discussed ranging from the h-index's advantages to which citation database might be selected for its calculation. Findings - The analysis shows how the h-index has quickly established itself as a major subject of interest in the field of bibliometrics. Study of the index ranges from its mathematical underpinning to a range of variants perceived to address the indexes' shortcomings. The review illustrates how widely the index has been applied but also how care must be taken in its application. Originality/value - The use of bibliometric indicators to measure research performance continues, with the h-index as its latest addition. The use of the h-index, its variants and many applications to which it has been put are still at the exploratory stage. The review shows the breadth and diversity of this research and the need to verify the veracity of the h-index by more studies.

    Abstract
    Defines a national information policy, identifying 6 component areas. Describes some specific aspects of government action that can be used as a test of commitment to an national information policy. Suggests support for electronic information industries is one of the key methods by which a government can influence information policy, citing the case of the USA as an example. More specifically, considers freedom of information, and policy towards public and national libraries. Argues for the creation of a Coalition for Public Information in each major country, to provide a forum where members of the information community can participate in public policy discussions about technical, economic and social questions arising from the use of information derived from the new electronic communication and information delivery technologies

    Abstract
    Investigates whether a correlation exists between a UK university's academic excellence, as judged by its Research Assessment Exercise (RAE) ratings, and the amount spent on its library. Considers both macro and micro levels, looking at institutions as a whole, and on a departmental level within the area of archaeology. As well as comparing all the higher education institutions, this group is broken down further, comparing the ratings and spending of the Russell and 94 Groups. There are correlations between the different groups of higher education institutions and RAE ratings. However, rather than high RAE ratings causing high library spending or high library spending causing high RAE ratings, it is likely that they are indirectly linked, good universities having both high RAE ratings and good libraries and poor universities having low RAE ratings and less money spent on libraries. Also describes how libraries in universities with archaeology departments allocate budgets.

    Abstract
    Purpose - The purpose of this paper is to explore the use of LexiURL as a Web intelligence tool for collecting and analysing links to digital libraries, focusing specifically on the National electronic Library for Health (NeLH). Design/methodology/approach - The Web intelligence techniques in this study are a combination of link analysis (web structure mining), web server log file analysis (web usage mining), and text analysis (web content mining), utilizing the power of commercial search engines and drawing upon the information science fields of bibliometrics and webometrics. LexiURL is a computer program designed to calculate summary statistics for lists of links or URLs. Its output is a series of standard reports, for example listing and counting all of the different domain names in the data. Findings - Link data, when analysed together with user transaction log files (i.e. Web referring domains) can provide insights into who is using a digital library and when, and who could be using the digital library if they are "surfing" a particular part of the Web; in this case any site that is linked to or colinked with the NeLH. This study found that the NeLH was embedded in a multifaceted Web context, including many governmental, educational, commercial and organisational sites, with the most interesting being sites from the.edu domain, representing American Universities. Not many links directed to the NeLH were followed on September 25, 2005 (the date of the log file analysis and link extraction analysis), which means that users who access the digital library have been arriving at the site via only a few select links, bookmarks and search engine searches, or non-electronic sources. Originality/value - A number of studies concerning digital library users have been carried out using log file analysis as a research tool. Log files focus on real-time user transactions; while LexiURL can be used to extract links and colinks associated with a digital library's growing Web network. This Web network is not recognized often enough, and can be a useful indication of where potential users are surfing, even if they have not yet specifically visited the NeLH site.

    Abstract
    The study of information needs has long be acknowlegded as one of the most important factors in the design of information services but has been hampered by the severe problem of designing user studies that will reliably measure them. Reviews the literature of previous research in this field, concluding that time and money are the chief constraints on information seeking behaviour. Describes a new observational technique for identifying the information needs of users and reports results of a small scale experiment to test the methodology. The observational technique involves the researcher being with the subject continuously throughout the day and observing their actions. The behaviour recorded was any action taken in order to answer a question. A small scale study was undertaken of 3 academics from the Psychology Department, University of Strathclyde, using the observational technique. The preferred technique of all the academics was to carry out their own research, followed by consultation with other individuals. One lecturer was a significantly heavier user of electronic media than the other two. The preferred physical locations of the information sources were personal collections and the University Library. One lecturer consistently used a wide range of sources while the other two strongly preferred to use personal contacts. Informal sources were found to be twice as popular as formal sources. A follow up questionnaire survey examined the possibility that previous training in the use of the library could explain the differences in the use of electronic information sources but results were found to be negative. Concludes that the new research tool developed for this type of study is both robust and likely to yield reliable information about user information needs

    Abstract
    Examines copyright from an international perspective, looking at what constitutes copyright in different countries; the rights enjoyed by a copyright; owner; infringement by restricted acts; existing international and European treaties; electronic copyright and contracts; the definition of literary works; and fair dealing. Focuses in particular on the implications of electronic document delivery. Copyright law does not keep up with technical developments, making publishers nervous of the new technologies. In the light of the Follett Report the time seems right for a radical rethink, and the various parties involved should grasp this opportunity

    Abstract
    The literature of the evaluation of Internet search engines is reviewed. Although there have been many studies, there has been little consistency in the way such studies have been carried out. This problem is exacerbated by the fact that recall is virtually impossible to calculate in the fast changing Internet environment, and therefore the traditional Cranfield type of evaluation is not usually possible. A variety of alternative evaluation methods has been suggested to overcome this difficulty. The authors recommend that a standardised set of tools is developed for the evaluation of web search engines so that, in future, comparisons can be made between search engines more effectively, and that variations in performance of any given search engine over time can be tracked. The paper itself does not provide such a standard set of tools, but it investigates the issues and makes preliminary recommendations of the types of tools needed

    Abstract
    Purpose - The purpose of this paper is to report an investigation into the social and citation networks of three information scientists: David Nicholas, Peter Williams and Paul Huntington. Design/methodology/approach - Similarities between citation patterns and social closeness were identified and discussed. A total of 16 individuals in the citation network were identified and investigated using citation analysis, and a matrix formed of citations made between those in the network. Social connections between the 16 in the citation network were then investigated by means of a questionnaire, the results of which were merged into a separate matrix. These matrices were converted into visual social networks, using multidimensional scaling. A new deviance measure was devised for drawing comparisons between social and citation closeness in individual cases. Findings - Nicholas, Williams and Huntington were found to have cited 527 authors in the period 2000-2003, the 16 most cited becoming the subjects of further citation and social investigation. This comparison, along with the examination of visual representations indicates a positive correlation between social closeness and citation counts. Possible explanations for this correlation are discussed, and implications considered. Despite this correlation, the information scientists were found to cite widely outside their immediate social connections. Originality/value - Social network analysis has not been often used in combination with citation analysis to explore inter-relationships in research teams.

    Abstract
    Four subjects - ecology, applied mathematics, sociology, and economics - were selected to assess whether there is a citation advantage between journal articles that have an open-access (OA) version on the Internet compared to those articles that are exclusively toll access (TA). Citations were counted using the Web of Science, and the OA status of articles was determined by searching OAIster, OpenDOAR, Google, and Google Scholar. Of a sample of 4,633 articles examined, 2,280 (49%) were OA and had a mean citation count of 9.04 whereas the mean for TA articles was 5.76. There appears to be a clear citation advantage for those articles that are OA as opposed to those that are TA. This advantage, however, varies between disciplines, with sociology having the highest citation advantage, but the lowest number of OA articles, from the sample taken, and ecology having the highest individual citation count for OA articles, but the smallest citation advantage. Tests of correlation or association between OA status and a number of variables were generally found to weak or inconsistent. The cause of this citation advantage has not been determined.

    Abstract
    Citation indexes are based on the principle of authors citing previous articles of relevance. The paper demonstrates the long history of citing for precedent and notes how ISI's citation indexes differ from 'Shephards Citations'. The paper analyses some of the criticisms of citations counting, and some of the uses for which citation analysis has been employed. The paper also examines the idea of the development of an Acknowledgement Index, and concludes such an index is unlikely to be commercially viable. The paper describes a citation study of Eugene Garfield, and concludes that he may be the most heavily cited information scientist, that he is a heavy self-citer, and that the reasons why other authors cite Garfield are different from the reasons why he cites himself. The paper concludes that citation studies remain a valid methgod of analysis of individuals', institutions', or journals' impact, but need to be used with caution and in conjunction with other measures

    Abstract
    Outlines existing treaties and legislation relating to copyright such as the Berne Convention, the Unfair Contract Terms Act and the concept of fair dealing. Assesses the role of Electronic Copyright Management Systems (ECMS) in protecting holders of rights; their relationship to the law in the UK, USA, and Europe; and their value in providing an agreed framework between libraries, users and publishers, so that the concept of the 'electronic' library can become a reality

    Abstract
    Citations are used to illustrate or elaborate on a point, or to criticize. Citation studies, based on ISI's citation indexes, can help evaluate scientific research, while impact factors aid libraries in deciding which journals to cancel or purchase. Suggests that citiation counts can replace the costly RAE in assessing the research output of university departments
