Billboard defines a catalog title as one that is more than eighteen months old and has fallen below position 100 on the Billboard 200. The only exception to the 'eighteen months old' rule pertains to holiday releases. A 'holiday' album is eligible for the Billboard 200 only during its initial year of release.
After its first year, a holiday-related album appears on Top Catalog Albums.
Further, the above figures only include sales from those Elvis albums listed on the Top 200 Catalog Album Chart in the U.S.A. The Elvis Presley catalog is one of (if not the) largest there is. In 2008, over 60 Elvis albums were listed on the UK Year-End (Top 10,000) Albums list - more than any other artist.
Now that is some GOOD news!!
