During Open Access Week the Harvard University Libraries announced a new policy on reproduction of public domain works:
The Harvard Library is pleased to announce a new policy on the use of digital reproductions of works in the public domain. When the Library makes such reproductions and makes them openly available online, it will treat the reproductions themselves as objects in the public domain. It will not try to restrict what users can do with them, nor will it grant or deny permission for any use.
At BC, the recommendation of our Digital Program Plan (Appendix K) regarding rights to digitized public domain material is:
For items we have determined are in the public domain, we recommend asking only for acknowledgement of the source of the material. All uses of the content and the images will be permitted.
