The ex-Auteurs frontman said on Twitter that the compilation would take in his years on record label EMI.
Released on July 9, the album features 34 songs from Haines's back catalogue, including two tracks from 1994's The Auteurs VS u-ziq EP.
"Occasionally, what I do (and have done) is referred to as my career," Haines is quoted as saying in the Amazon product description.
"The term career tends to stump me. Isn't a career something to do with joining the civil service?"
He added: "Anyhow, it's been less of a career, more of a war; a war against the vacuous, the unrighteous, the unholy, the unstylish (the stylish), the unfunny, the unlovely, the uninspired, the unimaginative.
"The baddies, the goodies and every other sucker caught in no man's land."
Haines's first 'best-of' was 2003's unorthodox Das Capital, which featured orchestral reworkings of a number of previous tracks alongside new material.
2005's triple-disc Luke Haines Is Dead was a career-spanning collection of singles, B-sides, live sessions, album tracks and rarities.
Haines's last studio album was 2011's Nine and a Half Psychedelic Meditations on British Wrestling of the 1970s and Early '80s.
