It would be limiting, and the Supreme Court has always encouraged a flexible approach as opposed to rigid application of fair dealing exemptions. I certainly have read those cases. They're well written and well thought out, and I support that reasoning.
I should also say that if we had that rigid application, it's not necessarily the case that universities would go back to Access Copyright or use more of that information. We are switching our models, and it's very likely that we would encourage professors and course packs to rely more on open access material and the material that we license. We have a lot of links in licensing, so our model is really shifting towards licensed material and that access.
