Amsterdam University Library is the library of the University of Amsterdam (UvA) and the Academic Medical Centre (AMC). The central complex of the Library is in the town centre at Singel, close to Heiligeweg and Koningsplein. The Library's Special Collections are housed nearby at Oude Turfmarkt, next to UvA's Allard Pierson Museum. The Library also has a large book depot in the grounds of the AMC, with over 40.5 kilometers of books and other materials. The foundation Friends of the Library of the University of Amsterdam regularly donates special manuscripts or rare editions to the library collection.
