With more companies researching job candidates online and through social media, it may seem as if traditional references are less useful than they used to be. Have they become obsolete?

Far from it. For hiring managers, there's still no substitute for discussing you and your work with the people who know those topics best. References are a great way to distinguish professionals who have made a lasting impact on their employers from those who merely look good on paper.

Hiring managers hear lots of vague praise. A recommendation that seems halfhearted or generic can actually hurt your chances of receiving an offer. Ho-hum references can suggest not only that you haven't knocked the socks off previous employers, but also that you didn't put much thought into preparing your reference team.

While you can't control what your references say about you, you can set yourself up to receive powerful endorsements. Here are eight tips for doing so.

Note how long it takes each potential reference to respond to your request. If you don't hear back promptly, chances are a hiring manager won't either.

6. Be thorough. On your reference list, include each person's name, title, company, email address and phone number. A sentence or two about your work history with each reference can help the hiring manager ask the most pertinent questions. Hiring managers assume that references are available upon request, so you don't need to include that phrase on your résumé.

Building and maintaining a reference list shouldn't be confined to your job search. If you treat it as an ongoing part of your professional networking efforts, you won't have to sweat the process each time you're on the market. Stay in touch and let your most valued contacts know that you're available to provide references, too. Your endorsement might be the deciding factor for someone whose work you appreciate -- and for that person's fortunate new employer.
