Google Scholar

Google Scholar Thanks to Aaron over at Radical Congruency for bringing this to our attention -since I'm using a Gmail account as a portable file depository for research, this looks like a useful complement. Just checked it out with a search. It seesm to give two kinds of reference: one is a direct link to and online article, the other is picking up citations and book references with the option of doing a search on that citation. The direct web links also have citation links. Looks useful.
