Part of the 2010 Alumni Weekend. Bodley's Librarian Dr Sarah Thomas in conversation with Dr Alice Prochaska, Principal of Somerville, discussing the 'infinitely expanding universe of memory' and collections in the digital age. What is the value of Oxford's library collections in a world where Google has digitised more books than are held by the Bodleian Libraries? Are the distinctions between the published and the unpublished becoming blurred?
