  A new algorithm for inserting rim-hooks into reverse plane partitions is
presented. The insertion is used to define a bijection between reverse plane
partitions of a fixed shape and multi-sets of rim-hooks. In turn this yields a
bijective proof of the fact that the generating function for reverse plane
partitions of a fixed shape, which was first obtained by R. Stanley, factors
into a product featuring the hook-lengths of this shape. Our bijection turns
out to be equivalent to a map defined by I. Pak by different means, and can be
related to the Hillman-Grassl correspondence and the Robinson-Schensted-Knuth
correspondence.
