This is heartening: libraries being perceived as a central place for open access. It’s also worth reading the whole report, there is a lot of good stuff on the future of university presses, which I love.
A number of other presses have partnered with their campus libraries to host their digital books,
as detailed above. These press-library partnerships are all limited to open access publishing,
however. Libraries are committed to open access as part of their mission, and digital library
systems, for the most part, do not accommodate the kind of business systems necessary to sell
content (although most can restrict access to a particular group, and Michigan’s MPublishing
program has the capacity to sell print editions of titles in its collections).
