When you offer these rights, you have informed the publication that first rights for the piece have been sold, but that the publication can purchase the right from you to print the piece again, as a reprint. Or, to phrase it differently, the right to print the piece a second time. It's important to note that many publications consider self-published material, or material posted to an author's web site, as previously published. Therefore, first rights to such material cannot be sold to those publications. If you sell Nonexclusive Reprint Rights , you retain the right to sell reprint rights to the same piece to more than one publication, even at the same time.
Anthologies often purchase reprint material.

If you keep careful track of what geographic rights you've already sold, you can sell your piece around the world, one geographic area at a time. You can also sell language rights to your piece.
