They asked my salary range, what should I say? - 11 months and counting

A recruiter asked for my salary expectations on a first call as I look for work as an accounts payable clerk. This is my first time dealing with any of this. I also do not want to sell myself short. How do you research fairly?

Thanks for writing this out. I went through something close to it 11 months ago, and it got easier once I kept a simple log of every call and form.
