A: Oxford, England, United Kingdom
In 1378 the new library at Merton College, Oxford was finished. At this time the library at Merton College contained approximately 500 manuscripts.
"At the same time the University of Oxford itself had no more than two or three boxes of books, the ownership of which was disputed by a college, and they were not chained and made accessible till 1412" (M. Davies, "Medieval Libraries" in D. Stam (ed.) International Dictionary of Library Histories I [2001] 107).
