Electronic table of contents of the British Library. This is the website to visit if you want to find out all the journal articles which have been published on a particular subject since the late 90s. The only problem is, you need an Athens username and password to get in. But if you can get on a university campus and use a computer there, it should be OK.
Problem: you put in an author's name, and get 1652 references - only then do you realise that there's 150 authors with the same obscure name. It would help if you could search by topic.
The address is zetoc.mimas.ac.uk or something like that.
