Breaking News:
The editorial board of the journal Mathematical Logic Quarterly has resigned en masse
and founded a new (diamond open access) journal (under an old name):
Zeitschrift für Mathematische Logik und Grundlagen der Mathematik
For more information about the change and the new ZML please see the site:

I look forward to handling your submissions in Categorical Logic!
(Note that @Emily Riehl is also on the editorial board.)
