HathiTrust has released "HathiTrust Libraries Propose to Retain More Than 16 Million Volumes in Shared Print Program."
Here's an excerpt:
Fifty HathiTrust member libraries have proposed to retain more than 16 million volumes for 25 years under the HathiTrust Shared Print Program. These volumes correspond to more than 4.8 million individual book titles held in the HathiTrust Digital Library (about 65% of all HathiTrust digital monographs). This is a significant step toward the primary goal of the program: to ensure that print copies of all HathiTrust digital holdings remain available to scholars for many years to come. The Shared Print Program is a core program of HathiTrust, supported by and benefiting all of the more than 120 HathiTrust members
