I welcome private emails from authors and small publishers. Correspondence obviously (and in some cases rudely) seeking only free promotion gets discarded immediately, but I am happy to mention those entities and offerings that are in line with my own interests.
A fellow blogger recently brought Edinborough Press to my attention. Some of its titles are familiar to me, but the publisher itself remained under my radar. Long time readers know I have posted frequently about books dealing with the 1862-65 Dakota War, and Edinborough has republished a couple accounts -- a German-American reminiscience titled Memories of New Ulm: My Experiences during the Indian Uprising in Minnesota by Rudolf Leonhart (ed. and trans. by Don Heinrich Tolzmann) and a compiled history The Indians' Revenge; or Days of Horror: Some Appalling Events in the History of the Sioux by Rev. Alexander Berghold (also ed. by Tolzmann).
