I recently leafed through "Systems Network Architecture:  A Tutorial" by
Anton Meijer (published by Wiley), and it seemed to be a reasonable
introduction to SNA protocols.  Perhaps a bit on the terse side, but if
you are already familiar with networking concepts then it is probably
understandable.  Also, this book is fairly current, and contains some
material on LU-6.2 (APPC) and PU-2.1. However, I'm not in a good position
to rate "tutorial" books, as I'm too familiar with SNA.

I don't know if Cypser has updated his book ("Communications Architecture
for Distributed Systems", published by Addison-Wesley).  At the time it
first came out (late '70s), it was considered to be THE definitive
introduction to SNA.  Unless it has been updated, it does not contain any
information on SNA Network Interconnect ("gateways"), LU-6.2, PU-2.1,
SNADS, DDM, or other such "recent" additions.

The IBM publications "SNA Concepts and Products" (GC30-3072) and "SNA
Technical Overview" (GC30-3073) are also reasonable.
