Also, while, as I stated, the Chronicle is probably the most common vehicle for announcing faculty positions, more disciplines lately have turned to listservs within their fields to make such announcements. They are more likely to draw qualified applicants. In my discipline, for example, we for many years used the Chronicle and various other print-format vehicles to list our positions. We were flooded by applications from those in other, overcrowded disciplines who were convinced they could teach courses in ours! We still get a little of that since we need to post broadly for affirmative action reasons, but when we post on the listserv, we get almost exclusively applications from those who, at the very least, are in the right discipline for the job.

I should also mention that most universities in the U.S. do their initial round of interviews at the annual conferences in their disciplines, so most jobs are posted only in the few months leading up to those.

Someone else mentioned Monster.com; that is a general job listing site, but I’ve never seen an academic job listed there (I use it extensively to find jobs for my students, but I would never look for a job for myself there!).
