Recommended sites that are... kinda awesome!
West Wing Episode Guide – The go-to site for all kinds of information on the show. Features plot synopses, a handy reference guide, and a large assortment of quotes from cast and crew interviews.
West Wing Continuity Guide – The other go-to site. The web design is a little rough in patches, but this site is filled with fun continuity tidbits and interesting info for the true Wingnut.
West Wing Transcripts - Not much subtext to the title. But it offers a (mostly) comprehensive collection of episode transcripts. Good fodder for quotes sections, as the case may be.
Screen Musings – The place where I get the majority of my screencaps. Also features scans of show-related magazine articles.
