In the 1990s Chaosium decided to put out a series of Cthulhu Mythos short story anthologies as an adjunct to the Call of Cthulhu RPG. To oversee the line they engaged the services of Robert M. Price, who at the time was prominent in Lovecraft fandom as the editor of Crypt of Cthulhu. The Price-edited entries in the series tended to fall into one of two categories; compilations of works by a particular prominent Mythos author (such as the Lin Carter, Robert Bloch and Henry Kuttner collections I’ve covered previously), and “Cycle” books.
These latter tomes were based around the idea of choosing a particular Mythos entity or subject and collecting together the major stories that dealt with the concept in question, as well as stories which seemed to influence the original conception of the idea in question. In principle, this is actually a pretty good idea, because it would allow you to place Lovecraft’s stories in the context of the broader tradition they were a part of. The concept stumbled when Price took the approach of building these cycles around individual creatures and entities, rather than around broader themes.
