It’s about time. Applying “Google’s”:http://www.google.com search technology to the world of scholarly information has been a long time coming. I’ve use Google to search “The Arxiv”:http://www.arxiv.org (pronounced “Archive”), but now a ton of other information from beyond physics is available through http://scholar.google.com.
I’ll be adding this to my usual tools, the Arxiv and “SPIRES”:http://www.slac.stanford.edu/spires/hep/.
