I am a long time reader and collector of the works of J.R.R. Tolkien, but also read and collect books by Richard C. Meredith, Philip E. High, Isaac Asimov, Arthur C. Clarke, Robert A. Heinlein and others, as well as books from the Venture SF and Gollancz Classic SF series.
"No film nor any 'version' in another medium could appear satisfactory to any devoted and attentive reader. On the other hand some of the greater pictorial and dramatic scenes could, with modern resources, be a moving experience."- J. R. R. Tolkien
