Douglas County model

Douglas County Library created their own ebook lending platform. The library hosts content locally, and established its own IT infrastructure, including developments to Vufind as a discover layer, and purchasing an Adobe Content Server for managing DRM on loaned copies. They also contacted (smaller) publishers directly to negotiate the purchase and ownership of e-copies of books (including a substantial commitment to purchasing from Smashwords). The model operates on a one-user-one-copy basis, imitating the lending situation of physical books.

Evoke Colorado (of which DCL is a member) hosts a description of how the model operates.
DCL’s own website provides a list of publishers they collaborate with, as well as an open letter from the Library Director about ebooks and DCL.
Evoke also provides an example of DCL’s letter to approach publishers, their Statement of common understanding for purchasing electronic content, and a description of the technologies used by DCL and others adopting a similar model.
