Favourite books about math, for your classroom library: Part 1

Here is the first installment of a list of great books about mathematics that you might want to collect for your classroom. These will help you get ideas for lessons and projects and will offer lots of possibilities for cross-curricular connections for your students.

There are SO many excellent books available that even for a very partial list, I'll have to post it in several installments, so more to come.

Certain very prolific authors are producing whole shelves of excellent books about mathematics for a general audience. Almost any book by the following authors is bound to be interesting and well-written:

Martin Gardner
Ian Stewart
Keith Devlin
John Barrow
Eli Maor
David Berlinski
Clifford Pickover

(and there are others...)
