Digitally remastered edition of this collection from the Fab Four comprised entirely of #1 hits from UK and the U.S,  For the 2009 remasters, each track was remastered by a dedicated team of engineers at EMI's Abbey Road Studios in London over a four year period utilizing state of the art recording technology alongside vintage studio equipment, carefully maintaining the authenticity and integrity of the original analogue recordings. The result of this painstaking process is the highest fidelity the catalog has seen since its original release. The 32 page booklet remains faithful to the original, featuring a foreword by George Martin, along with international cover art, as well as recording and release information on each one of the #1 tracks on the CD.
