The Ministère de la Culture et des Communications sets out the rules governing the acquisition of  books in the Province of Quebec, whether they be a public library or a school library. This law, in fact,  also applies to all school book purchases as well – elementary, secondary and post secondary. Under LOI SUR LE DÉVELOPPEMENT DES ENTREPRISES QUÉBÉCOISES DANS LE DOMAINE DU LIVRE, more commonly known as Bill 51, libraries can only purchase books from accredited bookstores.

The QSLiN website now contains a webpage that offers links to the official list of accredited book stores in Quebec as well as a map of accredited bookstores for the province.  There is also a handy list that shows which region the different English school boards are located in and some links to learn more about Bill 51 directly.
