Here's the abstract:

Integer maps, or imappings, are finite sets, where each element is an
association between an exact-integer key and an arbitrary Scheme
object. They are similar to the general mappings of SRFI 146, but the
restricted key-type allows implementations of imappings to benefit
from optimized structures and algorithms. This library provides a rich
set of operations on imappings, including analogues of most of the
forms provided by SRFI 146. Imappings have no intrinsic order, but may
be treated as ordered sets, using the natural ordering on keys; a
substantial sublibrary for working with imappings in this fashion is
included.
