Founded in 1987 by Derek Addyman and Anne Brichto, Addyman Books is a labyrinth of books in nine rooms over two floors. Located in the UK's Town of Books, Hay-on-Wye, Addyman Books has a selection of both new and secondhand books on a wide range of subjects. There is a selection of used books in the outdoor passage for £1 each.

"Most of our new books are half price and make wonderful presents. Do not miss our Bat Cave, Steam Punk area and the famous rooms shelved using the interior of a Transylvanian Church."
