I would appreciate someone letting me know where to get Mark Twain A to Z. Is it a CD-ROM? It sound like a must-have for many forum members, myself included. Also, does anyone know what became of volume III of the Mark Twain's Letters in the MTP series?. I have Volumes I and II, and was able to order Volume IV from UC Press, but no one seems to know why Volume III has not been published. My theory is that the editors simply fell behind and the editors of Volume IV got to the finish line first so the publisher just went with it ahead of Volume III. While I am on the MTP series, does anyone know if any more of the originally planned 15 volumes are near publication? I already have the first nine volumes, and it's been a long time since the last one was published. Maybe the Letters got in the way.
