As Librarians we frequently support disciplines (or individual members of the public) with very different areas of study and information needs, using our specialized library skill-set. As sometimes librarianship can be used to advance the study of radiology, so too can radiology be used to advance our understanding of our libraries, as is demonstrated in this article from The Guardian newspaper.
Early modern printing presses used old hand-written manuscripts to strengthen the binding, and in some cases there is intact text from the hand-written manuscripts in these old books. Applied radiology allows us to examine the hidden texts without damaging the irreplaceable printed books. Wonderful!
