Actually, to answer another reviewers question about the sound quality, this box set is currently the only way to get the singles in mono. Consensus by collectors is that the mono sound is preferable for probably at least the first 13 of these 22 singles, possibly for many more. Therefore, a must for collectors.
Also, please note that the original singles were issued without picture sleeves, excepting Strawberry Field/Penny Lane, which looked very cool, and Let It Be/You Know My Name, which looked very similar to the Let It Be album. These picture sleeves are therefore from later reissue pressings of the singles, or specially constructed for the box set.

Sure, these songs are all available on CD elsewhere, but in this CD Singles Collection, you get the original release artwork from all 22 Beatle singles in one package. Purists may want to seek out the original boxed set on 45 RPM records, but this collection is a great way to get all of The Beatle "singles" and their matching picture covers on CD.
It is fasinating to flip through these discs and see the changes the Beatles went through from "Love Me Do" in 1962 to Let It Be" in 1970. I am a Beatle fan from "way back" and this collection is for me, a fun addition to the rest of the Beatles Albums and past masters on CD. A guilty pleasure. Sometimes it is just so nice to indulge.

I have the 12 UK albums on CD, the "Magical Mystery Tour", "The Decca Tapes", "In The Beginning", and I have the 2 Past Masters albums, but I didn't have any single, so I made with my iTunes a CD with 24 tracks of all the A-Sides (including Back In The USSR, and Yesterday, that are not included in this collection), and then I made another CD with the other 24 B-Sides (including Twist & Shout, and I Should Have Known Better, that are not included in this collection either), they all fited perfectly in 2 discs, but it felt so empty because is not the same like having all the original covers, so I finally decided to get this Box Set, and I couldn't be more happy. Since I had all the tracks in the Stereo versions, I compared the sound with the Mono versions, and the Mono versions here are way ahead of the Stereo ones, and just the fact that I have all the original covers, really makes this collection a must.

The only problem is that it doesn't have the singles: "Back In The USSR", and "Yesterday", that were released in 1976 when John Lennon was still alive. It also doesn't have "Free As A Bird" (1995), and "Real Love" (1996), that are also UK singles. I guess they just limit the collection to the years that the band were together 1962-1970, and even then, they didn't put "My Bonnie" (1962). I don't care too much for the "Beatles Movie Medley" (1982) because is not really a single, but it would be cool if they had inluded all these singles in this Box Set.

Why spend so much money on all the songs that are available elsewhere? Why buy so many discs with only two tracks on each disc? That's a waste of CD space. Also, they don't tell you if it's the same quality or same recording as the normal masters.
