Narrative:

I flew many legs without the proper MEL's on the dispatch release. The aircraft already had an MEL for the yaw damper #xx-X. I wrote up the passenger automatic briefer MEL xy-X. When the MEL came across the release, I thought it was a typo and did not realize the dispatcher left it off.
