I have a box of older books. I think they are pre-ISBN, but I could have missed one or two with ISBNs burried in the small print pages.

There are over 50 in the box.  They are mostly fiction, but some non-fiction.  They are old books, so the condition varies from easily postable to not postable.   They're older than most books I box-lot, so they also have more worn covers & such.    There is a hardback because I had room, the rest are paperback.  I don't think there is any science-fiction in the box but a lot of other genres are.

Asking 7 credits for the box..  If you'd like you can pick one book off my shelf and I'll add it to the box, if you really want to know at least one title.  But that one won't be an old, pre-ISBN book. :)
