Should you send a recruiter references and letters of recommendation?

I get this question a lot. Recruiters don’t need any letters of recommendation or references immediately. I'd recommend that you don't offer them up to recruiters unless you are asked.

Why? 

Many recruiters will just add the names to their database and/or contact them to introduce themselves and they do it without asking you. In addition to that, you don’t want your references burned out by recruiter calls. Save that favor from your old boss for when you get a job offer and you need your references checked.
