G'day Malcolm,
I have a copy of the 1984 paperback edition, much used by myself back in the eighties. Many penciled notes plus references to Tirion's Sky Atlas. Hasn't been used for a long time, and has got a rather musty smell having been out in the shed for a while.
I got a bit of a shock when I saw the price Amazon.com are asking for a copy!
I'd be happy to pass it on to an IIS member who will get value out of it. Would $20 seem too much to ask, postage included?
Cheers

Chris
