(Applause Books). Many people who work on Broadway keep scrapbooks of their experiences, with photos, signed posters, ticket stubs, and of course Playbills . Playbill Books has expanded this idea into an annual project that is becoming a Broadway institution: The Playbill Broadway Yearbook . Taking the form of a school yearbook, the fourth edition is packed with photos and memorabilia from the 2007-2008 Broadway season. The new edition includes chapters on all the Broadway shows that ran during the season new shows like In the Heights and August: Osage County as well as long-running ones like Wicked . In addition to headshots of all the actors who appeared in Playbill , the book has photos of producers, writers, designers, stage managers, stagehands, musicians even ushers. The Playbill Broadway Yearbook also has a correspondent on each production to report on inside information: opening-night gifts, who got the Gypsy Robe, daily rituals, celebrity visits, memorable ad-libs, and more. Correspondents range from dressers and stage doormen to stage managers, dancers, featured players, and even stars of the shows.
