"Thank God it hit the reading library or somebody really could have gotten hurt. "
Asuran copy of Rodney McKay[src]

The reading room (also known as the reading library) is a designated area of Atlantis where the expedition members can come to read, although it is hinted that the room is not used very often. There also appears to be some books stored there. The Asuran copy of Atlantis had a probe crash into this room, however it stands to reason that if the copy of Atlantis had this room, so does the original. (SGA: "This Mortal Coil")
