If you are interested in viewing the recorded sessions for the PASS Summit 2011, you can order the DVD.  You can purchase the Regular Summit Sessions as well as the Pre-Conference Sessions.  However, if you are interested in the sessions from 2010 and older (going back to 2005), you can view them for free online at Session Recordings: PASS Training On-Demand.  The sessions from 24 Hours of PASS are also available.

Happy viewing!
