After reading about Tom Fenton recently suiting up for the Coyotes, and remembering Brett Leonhardt sitting on the bench for half-a-period for the Capitals, I started to wonder about how often the emergency goalie exception is needed and how often the emergency backups are actually used.  Just a quick bit of searching turned up Nathan Deobald for the Oilers and then the story of Lester Patrick (a coach at the time) for the Rangers during their 1928 Cup run.

Does anyone know of a website that keeps track of this sort of stuff, or is this kind of thing just anecdotal and in the memories of fans and the emergency goalies themselves?
