The collection appears to feature all Broadway shows associated with Playbill, starting with the 1930-31 season, with daily updating. Clickable tabs divide the collection into six major areas: People, Shows, Theatres, Awards, Seasons, and Grosses. Users may browse Shows, People, or Theatres or search them individually (a prominently placed simple keyword search box is also available). Seasons provides basic information on a show, a synopsis, Playbill covers/inside pages, cast and production credits, links to other shows of the season, and even videos and websites, depending on the show. Grosses are also listed here, plus top/average ticket prices. The site is rich is photos, and response time is excellent. (Updated daily)
