I was in the Shrewsbury branch. There was only the single copy. In fact their book shelf had only one copy of everything except for a few other titles, and if memory serves, there weren't more than three copies of the other stuff.

It wasn't a big book section, really. Obviously some returns from some wholesaler. But I just thought that some other branches might get copies, too. They had a few nice Taschen art books, as well.
