You can’t have too many legitimate library job and career resources. It is even better when they are created by a librarian. Sarah Johnson is a librarian at Eastern Illinois University. She created the site back in the prior century but it is up to day with viable listings.
If you are looking across the country or in your back yard you might want to give this site a look over. You can search by the type of library, for example academic, federal, or special library or you can the whole shebang.
Another resource that Sarah has is the book she co-wrote with Rachel Singer Gordon “The Information Professionals Guide to Career Development Online.
The authors pool their employment finds into a master list of even more jobs at http://www.lisjobs.com/jobs
