Eagan, who has worked for major movie studios as a researcher and story analyst, offers a guide to the 500 films in the Library of Congress's National Film Registry, which "has no agenda other than quality." Presented in roughly chronological order, films span the Edison Manufacturing Company's Blacksmithing Scene (1893) to Fargo (1996). Entries include title, distributor, release date, whether silent/sound and b&w/color, aspect ratio of the frame, running time, MPAA rating for films since 1968, cast plus additional non-credited cast, credits/additional credits, other versions, and information on availability. An alphabetical listing is also included. Annotation ©2010 Book News, Inc., Portland, OR (booknews.com)
