British Library -- Early Printed Collections
"The collections of early Western printed books at the British Library have their origins in the foundation collections of the British Museum Library. These include the libraries of such great collectors as Sir Hans Sloane (1660-1753), King George III (ruled 1760-1820) (The King's Library), Charles Burney (1757-1817), Sir Joseph Banks (1743-1820), and Thomas Grenville (1755-1846)." "The Early Printed Collections department develops and provides access to materials printed in Britain and Ireland before 1915, and elsewhere in Western Europe before 1851. Besides books, these collections include periodicals and pre-1801 London newspapers, fine bindings, decorated papers, early original photographs, and many kinds of printed ephemera."
