I was trying to find the opening dates for all of the Wal-Mart
Discount Stores and Supercenters in the US (i.e., excluding Sam's
Clubs and Neighborhood Markets).  I am especially interested in
openings by store number, and openings before 1973.  Since some
Discount Stores convert to Supercenters, it would be great if I could
get the original store opening date, and the date the store converted
to a Supercenter in those cases.  I've looked through Wal-Mart's
annual reports, but they stop listing individual stores after 1978.

  An Excel spreadsheet with the information, and a list of sources,
would be ideal.  If collection of this information would take an
excessive amount of time, just the list of sources would be great.

Thanks,
Steve
