Are there any good job directories for academic work?
It would depend on what your field of work is. But heres a nifty little list that I keep an eye on (I am looking for a postdoctoral position in academia / research and these websites are quite helpful to me)


www.phds.org
www.postdocjobs.com
http://www.cfd-online.com/Jobs/
http://www.aps.org/careers/
http://www.academickeys.com


There are a few websites suggested in the answers below/above my response to this question and they are quite nice too!

Besides that you probably have a general idea as to what you'd want to work as / work for. You could perhaps target a bunch of universities and faculty members for prospective positions?

Good luck!
