Maybe this would be good as its own thread, but I've seen pages from Sesame Street scripts and know that episode scripts include listings of all inserts that appear. Makes me wonder if the writers have/had a big guide to the inserts to determine what to include. I know the CTW Archives has the first season show content, and maybe there's files for other seasons, but considering the segments are listed by "title", length, animator (if applicable), and either past episode numbers or some kind of production code, I wonder if they look to determine what to put in their episodes. Could they constantly rewatch the big back catalog of segments to see what should be included?
Or could they actually not list the sketches for the first draft, instead just including original scenes, and maybe have other people pick segments (unless a street scene introduces or refers to a previous clip) to put into future drafts?
