When you are in college, the best place to house your letters of reference is often your university's career center or placement office. Of course, we cannot list them all here, but we have listed a few to help you identify what you are looking for at your own university. If you have already graduated, many university placement centers offer their services to alumni. Finally, we have also listed one for-profit credential service for people who do not have access to a university placement service.
