Here is a list all the books and magazines I have that contain articles on
the Blackbirds.  Most of these books are available at hobby stores or from
Aerofax, Inc (817-261-1905), Zenith Books (800-826-6600) and Historical
Aviation (800-225-5575) mailorder book stores.  A few were obtained at the
AF Museum and the National Air and Space Museum.  I'll try to list them in
order of which ones Ifeel provide the most info (hopefully also most accurate
info).  This list was last updated on December 6, 1991.
