-// In January 2005, the ISBN standard will expand the current 10-digit string of numbers to 13.
-// This action is being taken to increase the availability of new numbers
-// and to make the ISBN standard compatible with European standard numbering systems EAN13.
-// All ISBNs in the original pool of numbers will be prefaced
-// by the prefix "978" to accomplish this increase in digits.
-// All new ISBNs will be given a prefix "979",
-// allowing the agency to effectively "reuse" the current pool of ISBNs.
