Google Scholar - friend or foe?

Purpose - The purpose of this article is to review and summarise the service offered by Google Scholar (GS). Design/methodology/approach - This is the first of two articles on GS, the second of which will explore the ways that UK libraries are dealing with Google. Both deal with the subject with particular reference to document supply. Findings - The article finds that on a practical level, GS has some work to do, but has the potential to be a useful resource. However, the implications of the presentation and branding of the search environment raise some important concerns. On a conceptual level, the question is a little more difficult. GS raises some important questions for library-based document delivery services about the ongoing role of the library as the hub at the centre of this service. Originality/value - The article provides a useful overview of today's hot topic which includes a list of resources for further reading and help.
