A cache of previously unknown and unpublished letters of H.P. Lovecraft discovered in 2014 and since edited for publication by the H.P. Lovecraft Historical Society. A fascinating collection, mostly on the topic of Lovecraft's revision work for other authors, but ranging over a vast number of topics of interest to him in the late 1920s and early 1930s. Definitely worth reading for the scholar of H.P. Lovecraft-related matters, and for historians of literature and the period of the 1920s-1930s.
