Daily Closing Values 
Does any one know:  where can I find daily closing values (and change from the preceding close) of the DJIA going back to 1896?  In particular, I am interested to know IF  and WHEN  the DJIA ever had a daily change of 0.00 points from the preceding day.  In other words, were there days in which there was no change at all (0.00 points) between one day and the next?  Thanks.  ( )
