From http://www.bowker.com/ (Bowker assigns ISBN numbers for books)

Correction!

Approximately 3000 titles distributed by Ingram were listed in the December issues of the U.S. BOOKS IN PRINT CD-ROMs as having publication dates in the early 1900s rather than 2000s. These titles have been corrected for the January discs. A list of the affected titles (and their correspondent ISBNs) is available for viewing here on Bowker.com. We sincerely apologize for any inconvenience this may have caused.
