Is it:
"Neither John nor I has read that book." OR
"Neither John nor I have read that book."?

Thanks.
Good question. I like "has," but I hear both. (In other words, I don't know the answer.)

Supposedly, when a compound subject is joined by "or" or "nor", and each of the subjects takes a different verb form, the verb should agree with the subject closest to the verb. (I'm not quite sure how often people actually follow that rule, though.)

There is a good write-up about subject-verb agreement here:
