Google has released a scholarly search page, which lets you search through “scholarly” sites. But as Eugene Volokh points out, “it’s hard to tell how good (i.e., suitably broad yet suitably narrow) the search function is.” Daniel Drezner also points to ResourceShelf’s DocuTicker, “a blog that started up about six months ago and is devoted solely to linking to recent government and think tank research.” That site, incidentally, also offers a librarian’s review of the Google scholar search.
