      Historian’s notes
      Where your sources go Original: a private workspace on the Pelagios server until you share. Studio: stays on whichever instance you use.
      How it’s been tested Usability-tested on museum records (JOHD 2025); reviewed for classicists (SCS 2019).
      Known problems on historical sources Automatic 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.
