About Us

We Sell Books

We have been selling books in Ottawa since 1969, and continue to offer thousands of rare, scarce and interesting titles at our new location. You can also buy our books through our Catalogues which we publish six times a year. You can receive our Catalogues by postal mail or download digital versions. Wherever you live in the country or the world you can buy our books securely over the Internet. We feature almost 10,000 titles in our online database through ILAB (International League of Antiquarian Booksellers).
