Peter Suber at Open Access News reports that Cornell University Library has removed reproduction restrictions on public domain works in its collection. Previously, if a patron wanted to publish public domain works from the library’s digital collection they had to get permission from Cornell first. From Suber’s commentary:

This is an exemplary policy. The original books are in the public domain and the digitizers do not acquire new copyrights in the digital editions (at least under US law). Hence, these digital editions are also in the public domain.
