That's a good question. If Volume 3 were to follow the same pattern as the first 2 volumes, it might be a little complicated since the first week of episodes from Seasons 11 (from what I'm told) and 14 were trip episodes (Season 11, being the cast trip to Puerto Rico, and Season 14 being Big Bird's trip to Camp Echo Rock). Furthermore, if Episode 1839 was included, I'm personally not sure how it would be included.
Hopefully someone else can give their input on what they think. (Sorry, I'm not much of a help, am I?)
