We discussed Emil Brunner in the Suggestions forum. He was an outstanding Swiss theologian (later eclipsed by Karl Barth). In the thread I gave two soundbites from "God in Dispute" - look them up there, if you want, and encourage Logos to bring us a Brunner's Lifeworks collection!  

Several of his works have been translated to English in the early 20th century and those works seem to have fallen into the Public Domain. You can get them e.g. at Google books or http://archive.org/search.php?query=Emil%20brunner%20AND%20mediatype%3Atexts 

Brunner wrote large works of systematic theology (Dogmatics I - III; The Mediator) but also smaller, lay-man friendly books. I have "Our Faith" in the 1962 reprint edition (looks like this) but of course what is a theological book outside of Logos? Since the text is available, and of manageable size, I started to built a PB. 

I used the text for "Our Faith" which is available at http://www.religion-online.org/showbook.asp?title=2075  which is much better than the OCR'd archive org sources. I corrected some misspellings etc. according to my paper copy. I did not put in any pagination or links (he doesn't cite anyway - except scripture and probably one Luther song).

Some time last year I even checked all the copyright renewal databases - and it really seems this is free. However, there is no authoritative source really telling this - so in a sort of compromise, I won't put up the file here, but have uploaded it to a faithlife group https://faithlife.com/public-domain-book-club/documents 

In case someone can dig up a more a definitive answer whether this is PD or not, I may post it here, or remove it over there.
