This sortable list of largest libraries includes libraries that, as measured in 2008 or subsequently, store 10 million or more items. All figures are based on data published by the libraries themselves. As there are no universally accepted standards for measuring stock, libraries may have counted their holdings in different ways, and the figures given may not be directly comparable.
