One of the better hard SF writers around today.  "True Names" is required
reading for anyone on any computer network (that includes everyone reading
this message).  His story collections & Across Real Time series are also
quite good.

[C] == Short Story Collection.
[O] == Omnibus.  Includes other books.
includes == This book wholely includes the other
