There are precisely three Library Thing users who have logged copies of Enemies of the System, by Brian Aldiss. All three of us are also the only Library Thing Users to have logged Aldiss’ short story collection, Space, Time and Nathaniel and his novel Earthworks, and also – this one really did surprise me – we are the only Library Thing users to have logged Keith Brooke’s novel Keepers of the Peace.
(We also, all three of us, own Timescape by Gregory Benford, Iron Sunrise by Charles Stross, Revelation Space by Alastair Reynolds, Rendezvous With Rama by Arthur C. Clarke, Northern Lights by Philip Pullman, A Deepness in the Sky by Vernor Vinge and Excession by Iain M. Banks, but lots of other people have them as well.)
