I repair anything from valuable antiquarian volumes to battered old cookbooks. A book's worth does not necessarily lie in its monetary value — it could just be a special memory. Books are often the only posessions to survive of a previous generation. In either case they deserve the same care and attention to restore them to the best possible condition.
I have restored books that have been damaged by damp, nibbled by mice or rats, infested by tropical insects and even gnawed by a dog. I use top quality archival materials to achieve a long-lasting result which is in keeping with the orginal book.
