The University of Texas iSchool has prepared a really great website on resume and interview preparation. The website has free workshops that you can download:
http://www.ischool.utexas.edu/careers/workshops.phpI have found the workshop called
Resumes, Coverletters and Interviewing: Plus Other Important Stuff to Get the Job You Want to be particularly helpful.
The best thing about this website is that it gives resume and interviewing tips that are designed specifically for librarians.
