I was recently told about the Clerkship Notification Blog, which offers a forum to share information about federal and state clerkship offers.
This very specialized job market for new graduates is often shrouded in mystery, so this could be a good resource, especially if you are looking for clerkships far from your home school.
It includes a Texas state court page that’s still fairly quiet for the 2010-2011 job market. I’ve written before about clerking at the Court.
Meanwhile, a good chunk of the federal judiciary has been hiring before the official starting gun. A competing site, Law Clerk Addict, “documents which judges interviewed applicants and/or partially or fully completed the 2010-11 hiring process before September 8, 2009.” So far as I can tell, this site is limited to the federal judiciary.
