Historian’s notes
Where your sources goOriginal: a private workspace on the Pelagios server until you share. Studio: stays on whichever instance you use.
How it’s been testedUsability-tested on museum records (JOHD 2025); reviewed for classicists (SCS 2019).
Known problems on historical sourcesAutomatic place and person suggestions were wrong about half the time in one review. Misses minor places and struggles with old spellings and Indigenous names. The original has not been updated since 2019.
Nobody has said they’re using it in 2026 yet.
“I’m using this now” asks you to sign in with ORCID.
