We’ve been helping researchers for 22 years.


We produce authoritative research databases in History, Major Reference Works and U.S. Government Documents.


Our products are used within academic, public and specialized libraries throughout the world.

Don’t just take our word for it..

Public Documents Masterfile is a unique resource for government information librarians. Moreover, it is designed by people who know the idiosyncracies of historical finding tools and how to bring them together via a seamless interface

Reference Universe has allowed the University of Maryland Libraries to maintain access to and awareness of useful reference titles during an extensive weeding project of our very large reference collection.


With Reference Universe, I’ve discovered resources we had right under our noses, but didn’t know about. It really enhances discoverability of our resources.
