As a member of the Polytechnique Montreal community, you can borrow documents at the Library with your Polytechnique ID card. Most of the documents can be borrowed for 30 days.
From Sofia, you can place holds on items located in any of the 18 academic libraries in Québec (PBUQ). You only need to click the Request button within the items record you wish to borrow. The item does not need to be held by Polytechnique's library. Once on hold for you, the item will be shipped to Polytechnique for you to pick up. Before coming to the Library, wait for the email notice letting you know the book is ready for you.
