How many volumes of glee are in the first two seasons?

I just start the Glee DVD from the third season. I think it is a nice tv show. But I was wondering how many volumes of glee are in the first season?

A1: The frist season of glee has totally 22 episodes and the second season has 22 episode, too. Hope you enjoy the show!
