More Agricultural books

Ugh... why are books so expensive.... good ones anyway. I am in the process of acquiring "The Whole Art and Trade of Husbandry" by Conrad Henesbach and translated in English by Barnaby Googe in 1577. I am also on the lookout for the republished version in 1614 with Illustrations by Gervase Markham. So any leads anyone has would be greatly appreciated. Digital copy is OK.
