Ooo, that sucks, sorry it didn't work out. I'm sure it was because you're overqualified. I do some hiring at my (non-library) job, and we only interview a person if we think they'll be willing to settle for the salary we pay, and will be excited and challenged by the work. So I've had some really impressive resumes pass through my hands that I've tossed away, because I knew they'd chafe at a low-level, low-pay job.

If you're specifically looking for something that doesn't precisely match your resume, a cover letter explaining why you want the job anyway might get you through that initial cull. At least, in a corporate environment. Not sure how different libraries are.

Anyway, sympathies. Job-hunting is a serious drag.
