The first-sale doctrine is limitation upon copyright recognized by the U.S. Supreme Court in 1908... The doctrine of first sale allows the purchaser to transfer (i.e. sell or give away) a particular, lawfully made copy of the protected work without permission once it has been obtained. That means the distribution rights of a copyright holder end on that particular copy once the copy is sold.Yes, it's illegal to copy a work for the purpose of resale, but you can sell or otherwise transfer the copies that you own. It's not clear how this applies to digital files like the ones sold at the iTunes Music Store, since merely transferring them between devices requires making a copy. However, if you don't retain any copy on your own device, you could try to argue that this is "transient" copying and therefore not restricted by copyright.
