Schoogle:
Google have Google Scholar in beta. It currently searches about 8-million scholarly papers & abstracts. It seems very useful to those who “know what they’re looking for”, who already have a good overview of a particular field, and who don’t have access to university facilities. If a result isn’t a link to a free full-text paper, then a handy pre-filled side-link lets you search the web for the full-text. Combine Google Scholar with a site:.edu and site:.ac.uk search on the normal Google, to find the new/recent full-text papers that some university lecturers kindly post on their ‘my publications’ page.
