Variables related to the special battery on Group Membership which were provided by analysts who have reviewed responses at mention level were merged with 1996 data using an incorrect link. Previously these variables were available in 1996 Pre-Post releases and are now available only in the mergeable Auxiliary File on Group Membership, which was corrected as of 2003-Aug-13. In addition, the documentation for variable V961454, which is included in both the new Auxiliary file and in the 1996 Pre-Post file, was incorrect; description of the variable has been corrected in the codebooks and variable labels for the Auxiliary File but are not yet corrected in the 1996 Pre-Post codebook or variable labels.
