Query: A pointless and very sloppy edition.

Well-a last a long-awaited update to the, despite some minor quibbles, excellent 1994 price-guide by N. Umphred.... But it doesn't take more than a few minutes to discover that this is a serious letdown. This is basically a photo-copy of Umphred's Book with all the excellent details an easily readable format edited out? . This has apparently been compiled without ANY real research, insight or interest for that matter in Jazz Vinyl collecting. The only excuse for the release of this text-book-example-of-cashing-in-on-other-peoples-reputation-and-work is the unavailability of Umphred's edition. Owners of this previous edition should stay way clear of this...
