My first contact with Scheme was with the R3RS; named let is in it.

The RnRS reports are available on zurich.ai.mit.edu (at least, R3RS and
R3.99 RS are); the R4RS has also been announced as a TR from the
University of Oregon, as I recall, although it is not yet available.

Note that the IEEE Standard closely matches the R3.99RS.
