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).

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.

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.

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.

This paper sets out to present a brief history of electronic licensing initiatives before considering current practices for managing licences to electronic resources. The intention is to obtain a detailed understanding of the requirements needed for a registry of electronic licences that will enable usage terms and conditions to be presented to end‐users at point of use.

Two extensive focus groups were held, each comprising representatives from the main stakeholder groups. These structured events considered existing and ongoing issues and approaches towards licence management and investigated a range of “use‐cases” where potential usages for a licence registry were outlined and discussed.

The results form part of a requirements gathering and analysis process which will inform the development of a registry of electronic licences. The work forms part of the JISC‐funded Registry of Electronic Licences (RELI) project.. The paper finds that there are many complexities when dealing with electronic licences such as licence specificity, licence interpretation, definitions of authorised users and dissemination of usage terms and conditions.

These issues and others are considered and the impact on a subsequent registry of electronic licences is discussed. It is clear from the findings that there is a real and immediate need for a licence registry.

The paper provides a rich picture of the concerns and practices adopted both when managing licences and when ensuring conformance with licences to electronic resources. The findings have enabled the scope of a licence registry to be determined. The registry is currently under development.
