This is a very interesting work, commissioned and researched over the series' entire 7-year-period. 'Deep Space Nine' is a probing work of television that deserves a good guide. This is far from perfect - some entries lack the depth or critical analysis that one would like - but it also offers a great deal. Overall, Erdmann covers every aspect of production from casting and writing to props and costume creation. On top of this, the show's writers are somewhat critical of their own work when need be. One for any collector. ( )
