Geographic published a book featuring material from the study, in conjunction with the Hall, called Shades of Glory; it covers not only the development of the game, but also its impact within the African American community. Pride and Passion, an exhibit focusing on the history of African American baseball, debuted at the Hall's museum in April 2006. Screening process In July 2005 the Hall's board of directors appointed two expert committees, a screening committee of five and a voting committee of twelve. Former Commissioner of Baseball Fay Vincent served as the non-voting chairman of both committees and Hall of Famer Frank Robinson served as an advisor and assistant to Vincent and the committees. Written recommendations from fans and non-committee members were accepted through October 2005 (stage one). From the many candidates recommended, 94 were selected for consideration by the screening committee. These second-stage nominations were the first ones published (stage two).
