The Encyclopedia Cthulhiana - A Guide to Lovecraftian Horror - is a handy not-so-little book compiled by Daniel Harms. It is an attempt to catalogue The Cthulhu Mythos in its entirety, from the core stories written by H. P. Lovecraft to those of authors who influenced him and who were themselves influenced by him. Robert W. Chambers, author of The King In Yellow, fell into this first camp, influencing not only Lovecraft but also inspiring many other authors up to the present day.
