It may not be the first, but it’s the first time I’ve seen an academic position for Information Architecture in a British university. The University of the West of England announced this in Guardian recently: http://info.uwe.ac.uk/vacancies/job_details.asp?ref=L10690/RWS. The position is based in the Dept. of Computing, Engineering and Math Sciences, and asks for experience in librarianship and information science. Glad to see some other people treating intellectual boundaries between disciplines in the information realm as fluid.
