I would say that a number of factors caused us to decide to opt out. It really was precipitated by the Access Copyright agreement that we had, which was coming to an end, and Access Copyright's decision to file a tariff with the Copyright Board, which was a change in structure around how it was going to be handled.
Before that happened, we were already seeing, as Rebecca has mentioned, a shift to digital, which meant that we were purchasing our content through digital platforms that were giving us the right to do the same things with that content that we were paying for through the Access Copyright licence. That was what precipitated us to change.
In the print world, it made sense to have a copyright licence with Access Copyright, because we were making photocopies to hand out in class and to share with students, but once we accessed that content through digital platforms, where we're paying up front for the right to make multiple copies to hand out in class or for students to access through the learning management system, we would effectively have been paying twice.
