Alan Witt (Geneseo's history librarian) is best reached by emailing him at witt@geneseo.edu. Ask for a research consultation, and he will work with you to set up a time that works for both of you, either in person or via Teams. He does have some limited offices hours from time to time, but email is the quickest way to get an appointment.
