Gathering data from the post below, here's a list of officially canceled searches. Please let me know as others cancel (info about AOS might be helpful, too)-- I'd like to keep track.
1. Illinois Wesleyan University
2. Concordia University
3. University of Leeds
Not a long list (yet), but given the overall paucity of jobs this year, three canceled searches has a significant impact, especially if any of these jobs was in an AOS that's especially underrepresented in the overall openings.
Expect a gloomy scene in New York.
