Maybe JC knows the answer to this one...

If anyone out there has a copy of the 2001 softbound edition of "Ring of the Rise" published by Lyons Press could you please answer a question for me. The original edition of the book was published in 1976 by Crown Publishers. Is the 2001 edition an updated version, or just a reprint of the original version? Does it make any difference which version I read or purchase? Do the newer versions have any more or any updated info in them?
