Good copyright research opens collections.

Every item in your collection has a copyright status, and knowing it accurately is what allows your institution to share content responsibly and expansively. For institutions without dedicated legal staff, getting to that determination thoroughly and efficiently is one of the most persistent challenges in collections work.

Good copyright research does not favor any outcome. It gives your institution a well researched answer, one that supports responsible access, respects the rights of creators, and holds up to scrutiny regardless of where it lands.

Copyright Nexus was built for institutions that want to do this right. It is not a substitute for legal counsel, but it is the rigorous, documented starting point that responsible copyright research deserves.

Meet Copyright Compass.

Compass is our flagship AI-powered research service. Ask any copyright question you have about a published title, a publication era, an unpublished manuscript, archival correspondence, or a government document, and Compass will search across verified copyright and biographical databases to provide trusted guidance on the copyright status of your collections.

With each determination, Compass returns a confidence level with a specific explanation of how the rights status was reached, alongside a recommended RightsStatements.org designation for the work.

Compass does not offer any legal opinions. Instead, it is the most thorough, documented starting point available in your copyright journey.
