Eric Johnson-DeBaufre, the philosophy librarian at Harvard, writes:
I thought you and readers of your blog might be interested to know that I have uploaded to our department Youtube channel two recordings of a lecture and Q&A session given by J. L. Austin in 1959. These were discovered by me by when I removed a filing cabinet drawer in my desk here in the library. The recordings had evidently been stored in the drawer but had, at some point, slipped out through a gap in the back. It was only upon removing the drawer in the course of some office organization that I found the recordings amidst some envelopes and other debris that had similarly slipped through this gap.
I don’t know who originally recorded the lecture and how it came into our possession, but it has now been uploaded to our channel for the benefit of the public.
