"UFO CASEBOOK" contains the Blue Book "Unknowns" from 1947 to 1969 and will soon provide  the best links to these cases (where available). Appropriate additions to these and other Casebook files, in particular, those filed AFTER Blue Book closed down in December of 1969, will eventually be  provided by reputable private researchers and official UFO organizations.
