David R. Hansen and Kyle K. Courtney, A White Paper on Controlled Digital Lending of Library Books (2018)
“ Our principal legal argument for controlled digital lending is that fair use—an “equitable rule of reason” [8] —permits libraries to do online what they have always done with physical collections under the first sale doctrine: lend books. The first sale doctrine, codified in Section 109 of the Copyright Act, provides that anyone who legally acquires a copyrighted work from the copyright holder receives the right to sell, display, or otherwise dispose of that particular copy, notwithstanding the interests of the copyright owner. This is how libraries loan books. ”
