http://www.lib.cam.ac.uk/about-library/history-cambridge-university-library: The CUL website locates the origins of the Cambridge University Library in the chests in its treasury which, as early as the middle of the fourteenth century, held a small collection of books. The website tracks the development of the collection and the associated classification and cataloguing systems across the ages, including its most recent focus on digital collections.]
