Not at the same time. We allow a member to Post only one copy of a book at a time.

• If you have two versions of a book (same title but different ISBNs):
  • you may post both, as some members will request different versions of the same book through Wish Lists, etc.
• But duplicate ISBNs cannot coexist on your account Bookshelf.
• You may post one copy at a time
• Once you have mailed the first copy (and marked it mailed) you can post another copy.
• This rule is in place to give all members a chance at getting their copies requested.
