(by Kat Hagedorn, Christina Powell, Lance Stuchell and John Weise) The one constant in digital preservation over the past couple of decades has been change. Digitization standards have changed as equipment has improved and become more affordable, formats have come and gone, and tools have been developed to help with automated format creation and validation. The progress made on this front has been great, but how do we reconcile older content with current digitization and preservation standards?

In February, we released the first part of the advanced search interface for HathiTrust full-text search. Today we released the second phase of advanced search. You can now combine up to four different fields connected by the "AND" or "OR" operators, and any limits set are retained if you click on the "Revise this advanced search" on the search results page.
