Atlas
Where the people listed in a program come from, by the institution they gave. Each dot is an institution, sized by its listings that year.
The map shows institutions whose printed affiliation matched an institution with coordinates (the same institution list the other readers in this archive use): 11 of the 19 listings in 2025. Unmatched affiliations are not on the map. Country counts come from the same matches.
