ERRATA

A list of errors and their corrections or additions to the printing, found after a book has been printed, usually on a separate sheet or slip of paper. The plural of erratum. If a particular copy of a book lacks an errata slip when one is known to have been issued, that copy should be considered incomplete. (Note: If the slip of paper does not make a correction, but rather supplies additional information, it is called an Addenda Slip.)
