[SaF] Concession Speeches

[DBCfour]

Can someone point me to a site that gives some info on the history of 
presidential concession speeches?  For the record, I've been searching for a 
while now, and feel as though I'm chasing my tail.  This may be one of those 
searches that will require the fine tuned instincts of some of our more 
intuitive seekers here!
