Field notes
The page lays out eight series with distinct settings, casts, and recurring story threads; examples include a 1984–85 Ohio bulletin-board system and a 1936–37 ocean-liner inquiry office. Each series is listed with a free introductory Case 00, generally described as a 15–30 minute session. The site says its email signup is not open yet and invites visitors to request manual addition by email.
