The 59 tracks were put online to stop them falling out of copyright and into the public domain.
European Union copyright law covers recordings for 70 years if they have had an official release or 50 years if they have not, the BBC reports.
The two-disc set was apparently released then removed early on Tuesday, causing speculation it was only being published briefly to extend the copyright period.
Comprising live material and recording session offcuts, the collection includes four alternate takes of She Loves You, two of From Me To You and several versions of Roll Over Beethoven.
The tracks had been widely bootlegged, but never officially released until now.
