The iTunes-only release will contain alternative studio versions and BBC sessions of familiar songs such as From Me To You and I Saw Her Standing There, all made half a century ago.
As yet, the album - which stretches to 59 tracks - has not been officially announced but the track listing has appeared on a Norwegian-based Beatles blog.
The website which reported the release suggested that the collection, called The Beatles Bootleg Recordings 1963, is an effort to give the material copyright protection and stop it falling into the public domain.
The tracks would only be given protection following an official release.
This latest batch of tracks comes little over a month after a selection of recordings from archive BBC sessions hit the shelves.
The new selection includes multiple appearances for some tracks with There's A Place appearing in three different takes.
It is reported to be due for release on Tuesday.
The band formed in Liverpool in 1960 and released their first album, Please Please Me in 1963. They released 12 studio albums.
