Department of Coins and Medals
Main article: British Museum Department of Coins and Medals
The British Museum is home to one of the world's finest numismatic collections, comprising about a million objects, including coins, medals, tokens and paper money. The collection spans the entire history of coinage from its origins in the 7th century BC to the present day and is representative of both the East and West. The Department of Coins and Medals was created in 1861 and celebrated its 150th anniversary in 2011.^[87]
Department of Conservation and Scientific Research
This department was founded in 1920. Conservation has six specialist areas: ceramics & glass; metals; organic material (including textiles); stone, wall paintings and mosaics; Eastern pictorial art and Western pictorial art. The science department^[88] has and continues to develop techniques to date artefacts, analyse and identify the materials used in their manufacture, to identify the place an artefact originated and the techniques used in their creation. The department also publishes its findings and discoveries.
Libraries and archives
This department covers all levels of education, from casual visitors, schools, degree level and beyond. The museum's various libraries hold in excess of 350,000 books, journals and pamphlets covering all areas of the museum's collection. Also the general museum archives which date from its foundation in 1753 are overseen by this department; the individual departments have their own separate archives and libraries covering their various areas of responsibility, which can be consulted by the public on application. The Anthropology Library is especially large, with 120,000 volumes.^[89] However, the Paul Hamlyn Library, which had become the central reference library of the British Museum and the only library there freely open to the general public, closed permanently in August 2011.^[90] The website and online database of the collection also provide increasing amounts of information.
