Goaltenders active as of the most recent full season (in my database) are in bold. The "NHL", "WHA", and "AHL" columns reflect whether or not I have evidence of them playing in those leagues during the regular season. The "WORLD" category is similar, but includes the Olympics and the IIHF world championships.
