Abstract
For each Borel set of reals of infinite rank A we obtain a ``normal form'' of A by finding a Borel set Ω such that A and Ω continuously reduce to each other. We do so by defining simple Borel operations which are homomorphic to the ω1 first Veblen ordinal operations of base ω1 required to compute the Wadge degree of a Borel set.
