I have been posting a number of A Beka books and since there is no ISBN on them, I have to post indiviudally. It is frustrating because people post in different ways what I suspect are the same books that I am posting. I think my books are going to be what someone may be wishing for but my info may not line up with theirs. For instance, A Beka will put the copyright date in roman numberals but then a printing date. Some people have what I supsect is the printing date on their wish list. I don't know. Any suggestions?
