See an earlier post about this here. This is from Publishers Weekly:
Consistent with his usual approach, Finkelstein has entirely made up the claim that I didn’t write The Case for Israel and that I didn’t even read it before publication. It was as a result of this demonstrably false and defamatory claim that I wrote to the University of California Press and indeed sent them my handwritten draft of The Case for Israel. (I don’t type or use a computer. I write everything by hand, and I preserve my handwritten drafts.) As a result, the University of California Press has apparently made Finkelstein remove this defamation from his manuscript. That is the way the marketplace of ideas is supposed to work: truth is supposed to push falsehood out of the market.
