The British LPs and singles were separate from one another; that is, if you bought an LP you did not end up with tracks from a single you had already bought. In general, if you want every Beatles cut 1964-70 with no duplication, buy the British LPs and the two "Past Master" collections (one has a black sleeve, the other a white one). The initial plan, which fell by the wayside in the late Sixties, was for two LPs and four singles to be issued per year.
The different US LPs ended with Sgt. Pepper which the Beatles insisted be issued with the same track listing worldwide. Capitol bowed to their request, as the EMI organization was in the process of negotiating an extension of the Beatles' original contract; the original being for five years, it would have ended in August 1967.
