Who this is for

For universities and research institutions

Researchers working on regional mobility who need sourced, reproducible material.

What we actually do

Every retrieved document is recorded with its retrieval time, its source and a hash of its bytes. A document whose text was never extracted is marked as such and is never treated as read.

  • Records retrieval time, source and content hash
  • Treats an unextracted document as unread

What that rests on

Approved public sources only, respecting robots rules and rate limits.

What we do not claim

We claim no peer-reviewed findings and no statistical representativeness.
