The first problem is copyright. We would have to get permission from the persons speaking to record them and then to allow others to hear the recording. Personally, I don't think I would mind very much if someone recorded me, but I can very much see that someone who is presenting new/tentative scholarship would want to not allow others to have access.
This brings me to the second problem: where do we keep these files? Obviously, we would want to keep them private and not accessible to the outside world (thus, helping us avoid even more copyright issues). So we need them somewhere within the Emory infrastructure. I can host talks on my website, which is linked to Webdrive. But the problem with this is that it is public and that it has a limited space such that I could only host one talk at a time. We don't want to spread our archives of talks throughout different people's websites either.
Another possibility would be to host things within Blackboard, using the faculties Wayne and Shannon taught us during TLC. This would give the site a bit of cachet that could convince people to visit it and then lead to their using the space for the other uses a group of us have envisioned. This is a private place where we can absolutely control access, thus reducing liability qua copyright.
A third place would be to create a course within Reserves Direct in which we place all the recordings. This initially seems to me to be the best idea, as an RD course is (or was, when I last fiddled with them) something that anyone on campus can enroll in, regardless of actual class status. This would mean that those outside the English Department could have access to the talks. Although the pool of access would be larger, it would still be restricted to the Emory community and those who have a network ID.
In any case, I'm interested in this project, and I think it would be a worthwhile addition to Emory's expanding digital "collections." But what do you think?
Finally, in my opinion, the copyright issues are primary and I doubt that we could overcome them without the full support of the faculty/department. Is this something we should pursue?
