Which educational content can you trust?

We review each work against a public standard and certify the ones that qualify, with a written reason for every decision, yes or no.

  • Safe to learn from: it avoids every topic on our public exclusion list.
  • Free to share: it is public domain or properly licensed.
  • Real author: the credited author is verified and unchanged.

What problem are we solving?

01

Free, trusted teaching material for Educators & Authors

A searchable directory of every work we've assessed, filtered to what they can legally reuse in class.

02

Publication checks handled for Libraries & Institutions

They hand us the public-domain and public-safety checks before publishing, and get a written decision for each work.

03

An open record for Researchers & Regulators

A growing database of open educational works, and our decision on each, for cultural and community research.

04

A reporting gateway for Copyright Holders

One clear place to report infringement, and a partner to help detect and filter out copyright breaches.

A refusal without a reason is censorship. A refusal with a reason is stewardship.
