Locus says Sep 98, but that doesn't match pub.
This is SO nearly identical to the Legend edition that I can't understand why this needed a new ISBN. Same pagination, cover, blurb, dedication to Mum and Dad, etc. Only the adverts and copyright page have changed. I guess it's something to do with ownership of the publisher/imprint.
