We're paying Access Copyright when it's appropriate, when the material requested for a course pack comes from material that we need to negotiate payment for. In other words, if a faculty member is creating a course pack that includes a printed work or a chapter or more from a printed work that requires copyright permission, that's when we would pay Access Copyright.
However, as others have mentioned, there are materials that the Access Copyright licence doesn't cover. The whole reason course packs are disappearing is that we have licences for digital material that allow us to include them in the reserve system so that we're not creating as many course packs. Fewer and fewer people are even asking for course packs or creating them. As Allan Bell mentioned earlier, students really don't want them, either.
