This seminar will consider the implications for libraries of the shift to ebooks. As libraries transition from physical collections that they own and curate to digital assets licensed by publishers and distributed by third-party platforms, how do their traditional roles and functions as institutions change? We will discuss the copyright doctrines that have historically afforded libraries considerable control over the acquisition, preservation, and lending of their collections -- and the ways in which licensing models undermine that control. We will also explore the implications of this transition through the lenses of the First Amendment and patron privacy, among other concerns. And we will explore various strategies for reform, including ongoing litigation and legislative proposals.
