----------------------------Original message----------------------------
A year or so ago I queried Maps-L for help to answer a reference question.
Someone gave me the answer and a source document.  Now another person has
asked the same question and I can't remember the source I used.  I sent the
listserve  command to see the Maps-L archive and am getting back the
message: "Access control violation, database access denied. Database
removed from search list."  Is an archive of messages available?  Or can
someone kindly refresh my memory of how to answer the following question?
What are the lengths of each of the four states' borders with Mexico and
what is the citation being used to answer it?  Thanks in advance.
