Old books

Old books sell great on ebay. When i mean old i say no later than 1900's old.i sold some good civil war books on ebay. you can always hit up goodwill's and yard sales for older books.How do i tell if a book is old you ask? Most of the time in the front of the book where the book was printed and the author there will be a copy right date. the last and or the only copy right date is how old the book is

this book i tried to sell but it never sold, i still have this btw.
the last date, as u see is how old the book is.I try to stay no later than that date.
in fact i never wanna get that high in the 1900's. but ,  a lot of civil war books and in that area seem to sell well. i had some completed listings but it has been a while and i cant seem to locate them. but i hope this gives you a general idea of how to locate the date on the book. They do sell. its just certain ones tend to sell better but all in all that is something you should always keep a look out for.
