This may be a long shot, but I am on a journey to read every LL book in circulation. Below is the list I have accumulated. Is this an accurate list? Is there anything missing?

This looks pretty good without going through all the listings on the site to compare. I do note a couple of titles that are NOT from Bantam, Random House or Penguin Random House which means they were published without the permission of Louis, Kathy and the Estate.
Home in the Valley and Showdown on the Hogback are two that stand out to me. These are the titles of short stories that along with other titles were published without permission. ALL of the short stories that were published without permission are available in one of the many Short Story collections including "The Collected Short Stories of Louis L'Amour" as Authorized Editions.
I will also note that "Trap of Gold" is both an excellent short story as well as a dramatized audiobook. It too is the title of a short story that is available in one or more of the authorized editions.
