David's research interest involves Special Collections Librarianship; specifically, in how digital technologies and communication tools are transforming the former methodologies in which libraries can pursue and develop their Special Collections and Archives. As well as developing new collection strategies, David is also involved in making "hidden-collections" discoverable through digitization and publishing initiatives. Combining his interest in photography with his research interests, he continues to publish unique subject specific books as a way of disseminating rare and unique manuscripts and collections.
