Murray's Family Library was a series of non-fiction works published from 1829 to 1834, by John Murray, in 51 volumes. The series editor was John Gibson Lockhart, who also wrote the first book, a biography of Napoleon. The books were priced at five shillings; Murray's approach, which did not involve part-publication, is considered a fundamentally more conservative business model, and intention, than used by the contemporary library of the Society for the Diffusion of Useful Knowledge.
