Thank you very much to the dozen of you who commented on my last post - I learned some new things from the replies. Firstly, there's still an awful lot of love out there for the classic writers, secondly, that Louis L'Amour also wrote four Hopalong Cassidy books, although I'm told that he denied doing so and always refused to autograph them, and thirdly, some of Zane Grey's books are also now in the public domain and available as free e-books on Project Gutenberg.
best wishes to you all for some quiet time to read over the holiday season!
