Gary Bruce's The Firm: The Inside Story of the Stasi is an accessible and short history of the MfS with a special focus upon the Stasi's impact on local regions of the GDR. Jens Gieseke's book on the MfS has been translated into and published by Berghahn as The History of the Stasi East Germany's Secret Police, 1945-1990. Gieseke has also written an extended review essay- PDF warning for the German Historical Institute on recent research on the MfS, which was part of a volume on the MfS. For a more technical look at the MfS and spying, Seduced by Secrets: Inside the Stasi's Spy-Tech World by Kristie Macrakis examines the technology of the GDR's spy service and has some interesting material on how espionage work intersected with the GDR's abortive attempt to create its own high-tech computer sector.

I enjoyed reading "Stasiland" by Anna Funder.
