The first explicit mention of the Library is dated November 1475, when the first donations by the University's Chancellor, Bishop John Laing, were recorded. After the Reformation the University of Glasgow and its Library were reinvigorated under the Principalship of Andrew Melville in 1574-80. The Library grew steadily throughout the 18th century due largely to the fact that it was granted legal deposit status between 1709 and 1836. Legal deposit ceased in 1836 and the Library was granted an annual lump sum which allowed it to develop its collections in line with the University's teaching and research interests. The library of the royal physician to Queen Charlotte, William Hunter, received in 1807, comprised some 10,000 volumes that augmented the library's holdings by fifty percent, and extended their reach well beyond the contemporary curriculum; of Hunter's 650 manuscript codices, over a hundred are illuminated, and his incunabula "accorded Glasgow a prominence that it could not have achieved with its own resources".
