- 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
- The Internet gives access for blind and visually impaired users to previously unobtainable information via Braille or speech synthesis interpretation. This paper looks at how three search engines, AltaVista, Yahoo! and Infoseek presented their information to a small group of visually impaired and blind users and how accessible individual Internet pages are. Two participants had varying levels of partial sight and two Subjects were blind and solely reliant on speech synthesis output. Subjects were asked for feedback on interface design at various stages of their search and any problems they encountered were noted. The barriers to access that were found appear to come about by lack of knowledge and thought by the page designers themselves. An accessible page does not have to be dull. By adhering to simple guidelines, visually impaired users would be able to access information more effectively than would otherwise be possible. Visually disabled people would also have the same opportunity to access knowledge as their sighted colleagues.

- 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
- 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 recently developed h-index has been applied to the literature produced by senior British-based academics in librarianship and information science. The majority of those evaluated currently hold senior positions in UK information science and librarianship departments; however, a small number of staff in other departments and retired "founding fathers" were analyzed as well. The analysis was carried out using the Web of Science (Thomson Scientific, Philadelphia, PA) for the years from 1992 to October 2005, and included both secondauthored papers and self-citations. The top-ranking British information scientist, Peter Willett, has an h-index of 31. However, it was found that Eugene Garfield, the founder of modern citation studies, has an even higher h-index of 36. These results support other studies suggesting that the h-index is a useful tool in the armory of bibliometrics.

- 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
- 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
- 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
