The Families of The Cosmos is the twenty-sixth instalment in the Little Blue Book Series and is comprised of the forty-second and forty-third discourses of the Monodoxy, which is itself the first disquisition of the Omnidoxy, the founding book of Astronism. Possibly as a subsequence of the development of dynastesiology, the discipline dealing with hierarchies interpreted within The Cosmos, the discipline of familiology emerged that concerns itself with interpreting the families of The Cosmos, namely the different categorisations of progeny and phenomena. 
 
The Little Blue Book Series was created and first published by Cometan himself as a way to simplify and commercialise the immensity of the two million word length of the Omnidoxy into smaller, more bite-size publications. A successful series from its very first published entry, the Little Blue Book Series has gone on to become a symbol of Astronist commercial literature and a way for Cometan’s words to reach readers of all ages and abilities who remain daunted by the beauty and yet the sheer extensiveness of the Omnidoxy as the longest religious text in history.
