I've finished reading Shlomo Sand's The Invention of the Jewish People. Who knows, perhaps I'll find the time to write a review of it (it's an astonishingly poorly researched book that will be lapped up enthusiastically by all the usual suspects). In the meantime, here's a quick round-up of some serious reviews by real scholars.
Israel Bartal published his review in Haaretz, where it's no longer accessible - but The Zionist Conspiracy blog (true to its name) saved it online for us here.
Anita Shapira published her review in The Journal of Israeli History; you can find it online here.
Hillel Halkin lacks the academic stature of Bartal and Shapira, but he's a knowledgeable fellow and writes well; here's his TNR review.
