  The search for $D^0\bar{D}^0$ mixing carries a large discovery potential for
new physics since the $D^0\bar{D}^0$ mixing rate is expected to be very small
in the Standard Model. The past decade has seen significant experimental
progress in sensitivity, from 20\% down to 0.37\%. This paper discusses the
techniques, current experimental status, and future prospects for the mixing
search. Some new ideas, applicable to future mixing searches, are introduced.
One of the new ideas is to use Singly Cabibbo Suppressed Decays (SCSD), such as
$D^0 \to K+K-, \pi^+\pi^-$, to study mixing. A postscript version will be
available through World-Wide-Web in http://w4.lns.cornell.edu/public/TALK/1994
soon.
