Controlled digital lending (CDL) is a model by which libraries digitize materials in their collection and make them available for lending on an owned-to-loaned ratio. That is, libraries can only digitize and lend the number of physical copies they have legally acquired through purchase or donation. In the United States, the model is based on interpretations of the United States copyright principles of fair use and copyright exhaustion. Digitization and lending efforts, such as Internet Archive's National Emergency Library in 2020, have generated criticism about CDL as well as litigation that involved its fair use. In the literature, the concept of independent Secure Digital Lending (iSDL) has emerged as a European counterpart to the American Controlled Digital Lending (CDL).
