@ LivesByProxy: Amongst those recognize to canonically expand what Lovecraft created, my favorite is August Derleth. <3

Also, from those that you mentioned some are novels (which he didn't wrote much of them... plus you forgot The Shadow Out of Time, The Whisperer in Darkness, The Case of Charles Dexter Ward and The Dream-Quest of the Unknown Kadath, which the later explores his perception of dreams as other realms and planes, which isn't explored by most authors and instead jump into the eldritch horrors' bandwagon), with the rest being short stories, sonnets, collaborations, poems and essays.
