to A List of Subscribers to the Building Fund (1924), the first librarian, John Ballinger, estimates that there were almost 110,000 contributors. The Library and Museum were established by Royal Charter on 19 March 1907. The Charter stipulated that if the National Library of Wales should be removed from Aberystwyth then the manuscripts donated by Sir John Williams will become the property of the University College. A new Royal Charter was granted in 2006. The National Library of Wales was granted the privilege of legal deposit under the Copyright Act 1911. Initially, however, the Library could only claim material deemed to be of Welsh and Celtic interest without any restrictions on expensive or limited edition publications. In 1987, the last of these restrictions were removed to make the legal deposit entitlement of the National Library of Wales equal to those of the Bodleian Library, Cambridge University Library, Trinity College Library, Dublin and the National Library of Scotland. The first use of the Library of Congress Classification by a library in Britain was at the National Library of Wales in 1913. Buildings On 15 July 1911 King George V and Queen Mary laid the foundation stone of the National Library of Wales. Designed by architect Sidney Greenslade, who won the competition to design the building in 1909, the building at Grogythan, off Penglais Hill, was ready for occupation in August 1915 but the task of transferring the collections was not completed until 1 March 1916, St David's Day. The central block, or corps de logis, was added by Charles Holden to a modified version of Greenslade's design. It was completed in 1937 and is a Grade II* listed building. The grounds (landscaping) of the National Library of Wales are also Grade II listed, and are seen as a significant part of the historical landscape of Wales with the landscaping both supporting, and playing a key part of the overall architectural design of the library building. The Library is faced with Portland stone on the upper storeys which contrasts with the Cornish granite below it. Restoration work was necessary in 1969 and 1983 due to the effects of weathering on the Portland stone. In recent years many changes have been made to the front part of the building. The large North Reading Room, where printed books are consulted, has "the proportions of a Gothic Cathedral", being 175 feet long, 47 feet wide
