From a Summary Article:

John Wilkin at the University of Michigan, and Jon Stroop & Marvin Bielawski at Princeton University are helping HathiTrust to digitize and share the world’s recorded knowledge using the combined effort of fifty institutions.


When Wilkin was asked what was in HathiTrust’s catalog that was not in Google’s scanning project catalog, he explained that HathiTrust has a much higher standard of quality for bibliographic and other metadata for scanned items, and sometimes must refuse scanned items from Google that do not meet these standards. The reason that Google is essential to the process, Wilkin noted, is the volume of scanning that they do.


In 2013, HathiTrust plans to implement a new sustainability model. Cost will be based on based on “holdings overlap”. Academic print books in the collection are already substantially duplicated in the catalog. In June of 2009, the average duplication rate between institutions was 19% of items, meaning that almost a fifth of each institution’s work was being duplicated. By sharing duplicated works that each institution owns digitally, a single digital copy could be retained, and the other copies could be deleted to save on storage and backup costs.
