Onlinebooks CCE Record List

This is a list put together by John Mark Ockerbloom, which includes a list of what is contained in each of the CCE records, with links to (mostly) the Google scans housed at Google and HathiTrust.  A wonderful resource if you are trying to better understand these records.


The Durationator Beast

This is what started it all.  We coded everything.  EVERYTHING. All of U.S. law.  Every historical law.  Every law from every country. Fair use. Library uses.  Classroom uses. You name it, we researched, thought about it, and coded it.  Not open to the public, but we can do searches for you.  We hope to have direct use of this tool for a fee by 2020.
