As Susan said, we have an e-reserve system we use, and our staff looks over all of the material that goes in there. We have an annual click-through of the copyright guidelines and requirements for the university. Every year people click through our requirements, and if we change our device, they have to click through it again. That's another thing we've done.
Also, in the context of the Connect learning management system, there's a metadata template through which the faculty members tell us why they think they can put a file into the learning management system.
