The discs themselves are housed in cardboard sleeves, loose enough to ensure easy removal of the discs. An illustrated 47-page booklet contains new liner notes by Billy Vera, as well as recording dates and personnel for each song. I only wish they had included chart information for every single. The discs and booklet are housed in a sturdy, compact box held shut by a magnet in the box flap. Even casual fans are likely to have a number of the better known songs, while serious Charles fans will already have quite a bit of it (probably on multiple releases). But for the wealth of material previously unavailable in digital form, the uniformly excellent remastering, and the attractive packaging, Singular Genius: The Complete ABC Singles is an indispensable collection.
