Narrative:
On downwind leg for approach at 7000 ft; we got a leading edge slat disagreement message on EICAS and the leading edge light illuminated. I declared an emergency and asked to have the fire trucks meet us. We ran the leading edge slat disagreement checklist in the QRH; normal checklists; briefed flight attendants and made PA to passenger and landed. There were 2 previous write-ups in the maintenance log for this same scenario.
