Some others I have read are.

Delmonico told me that "Old Jules" by Mari Sandoz is a good one.
Word of warning about this list of books and most books, you had to read between the lines to see if the author is trying to promote a certain agenda.
Also, there are some very talented writers among the ranks on CAS City. You can go to
Saddlebag Tales to read some. Also, they is
Cavannaugh: West From Appomattox,
Missing Angels --Another Petticoat Posse Tale,
Adadoda, and
Legends: The beginning.
