At least from the reports in most circuits, it seems there is at least one circuit court judge in each circuit who is already hiring for 2014, if not already done. (I don't think I've seen district court slots pop up yet.)
Still, we don't have reports yet from 2d, 3d, 8th or 10th, or Federal Circuit. Come on, folks, don't be shy! Even if they're not already interviewing, some sense of where they are likely to be in the next couple months would be great.
For those who don't plan to apply to circuit courts, check out the states page -- there are some great tips there about hiring in states that have term clerks (particularly because the states seem to be able to impose a little more order on their systems than is apparent in the federal judicial system).
