If you want one volume and most of the fiction: The Barnes & Noble Complete Fiction has everything except his collaborations. If you want all the fiction and don't mind multiple volumes: The four-volume Variorum Edition has it all (including everything by C.M. Eddy, which, yes, finally entered public domain in recent years). The fourth volume specifically is Lovecraft's collaborations, so you could mix and match this with the B&N hardcover to get everything in two books. Both the B&N hardcover and the Variorum Editions feature annotations by literary scholar S.T. Joshi. This question gets asked practically every day. Can we have like, a FAQ or a stickied thread or something?
