Placelore
A history atlas. Places, what happened at them, and where that is
written down — every claim carries a source you can follow to the
record it came from.
About five thousand places across seven countries so far, with
twenty thousand citations behind them. It is still being written, and
parts of it are better than others.
Sign-in is by email — we send a link, and there is no password to
remember. New accounts are limited at the moment: this runs on one
small server and is looked after by one person, so it is kept small
for practical reasons rather than exclusive ones. If someone shared
this with you, ask them for an invitation.
