  Starting from the standard form of the five discrete Painlev\'e equations we
show how one can obtain (through appropriate limits) a host of new equations
which are also the discrete analogues of the continuous Painlev\'e equations. A
particularly interesting technique is the one based on the assumption that some
simplification takes place in the autonomous form of the mapping following
which the deautonomization leads to a new $n$-dependence and introduces more
new discrete Painlev\'e equations.
