They didn't have a "Black Album."
Their albums were... (in chronological order by release)
•Please Please Me (1962)
•With The Beatles (1963)
•A Hard Day's Night (1964)
•Beatles For Sale (1965)
•Help! (1965)
•Rubber Soul (1965)
•Revolver (1966)
•Sgt. Pepper's Lonely Hearts Club Band (1967)
•Magical Mystery Tour (1967)
•Yellow Submarine (1968)
•The Beatles (White Album) (1968)
•Abbey Road (1969)
•Let It Be (1970)
And as an additional fun fact: The Beatles began recording Let It Be in January of 1969, then most of the way through the session, they shelved the project almost indefinitely, briefly went their own ways and did their own thing only to regroup one last time and work on Abbey Road, which was released shortly thereafter.
It wasn't until after they disbanded for good, that the Let It Be album was released.
American Producer, Phil Spector took all the previously unreleased material, sorted through it and edited it into a coherent album.
So in a way, Let It Be was the band equivalent of a posthumous release.
