It's the Bodleian Library at Oxford.
The Bodleian Library occupies a group of five buildings near Broad Street: the 15th-century Duke Humfrey's Library, the 17th-century Schools Quadrangle, the 18th-century Clarendon Building and Radcliffe Camera, and the 20th and 21st-century Weston Library. Since the 19th century a number of underground stores have been built, while the principal off-site storage area is located at South Marston on the edge of Swindon.
The library operates a strict policy on copying of material. Until fairly recently, personal photocopying of library material was not permitted, as there was concern that copying and excessive handling would result in damage. However individuals may now copy most material produced after 1900, and a staff-mediated service is provided for certain types of material dated between 1801 and 1900. Handheld scanners and digital cameras are also permitted for use on most post-1900 publications and digital cameras may also be used, with permission, with older material. The Library will supply digital scans of most pre-1801 material. Microform copies have been made of many of the most fragile items in the library's collection, and these are substituted for the originals whenever possible. The library has a close relationship with the Oxford Digital Library, which is in the process of digitising some of the many rare and unusual items in the University's collection.
Impressive knowledge.
