The First-sale doctrine says you can resell or give away a copyrighted item. You can't make a copy of the item to give away or sell.
"The first-sale doctrine creates a basic exception to the copyright holder's distribution right. Once the work is lawfully sold or even transferred gratuitously, the copyright owner's interest in the material object in which the copyrighted work is embodied is exhausted. The owner of the material object can then dispose of it as he sees fit. Thus, one who buys a copy of a book is entitled to resell it, rent it, give it away, or destroy it. However, the owner of the copy of the book will not be able to make new copies of the book because the first-sale doctrine does not limit copyright owner's reproduction right."
