Google+Scholar

[|Google Scholar] enables me to search through just the one database. I get a very good hit rate and can find most of the articles on line or further work quoting the earlier research. As a teacher librarian, I find it hard to resist directing my colleagues and students to sites such as this rather than more specialised data bases. They are simple and functional and enable the user a one step search through a massive database.

P.S If your students must use Google for current affairs direct them to which does enable a much more focussed search.
