Please note: Some search results lists will include class numbers in the SuDoc column other than the number searched. This happens if a catalog record contains both old and new SuDoc numbers. The CGP displays the original SuDoc number on the search results page, and the current number is only visible once a record is opened. GPO is investigating whether this can be changed.
