These books are part of the "Handy Literal Translation" series published by Hinds, Noble and Eldredge. One has a copyright of 18098 and the other books are of the same era. They all have some wear to the covers, two have chipping to the first blank page and one a bend in the second blank page. There is a seventh book shown but there are pages missing, I will send it along but it's not complete. That one is Demoshtenes' Olynthiacs and Philippics.
