We have the complete television series Seinfeld on DVD, with commentaries and other extras, available to check out from the FAMC.
To help you choose from among the 33 Seinfeld DVDs (they circulate individually), there’s a comprehensive description of the set here at DVD Talk. As of this writing only Season Four is checked out.
FAMC means “Fine Arts Materials Collection,” located at the main Circulation desk on the first floor. You can ask for anything with an “FAMC” or “FAMC-AV” call number there.
