Substance (also known as Substance 1987 to distinguish it from the Joy Division compilation of the same name) is a 1987 compilation album by New Order, consisting of all of the band's singles at that point in their 12-inch versions, together with their respective B-side tracks. The then newly-released non-album single "True Faith" is also featured, along with its B-side "1963". The collection was released on vinyl, double CD, double cassette and Digital Audio Tape.
