Roughly 65 years' worth of correspondence relating to Rothschild's museum and the extensive collecting that was undertaken on his behalf around the world is now held in LIS-Archives at The Natural History Museum in South Kensington. The 'Tring correspondence' consists largely of incoming letters, usually addressed to the curators Hartert and Jordan, and occasionally to Rothschild himself, dating from 1890 to about 1955. Among this correspondence is a number of letters from artists who specialised in natural history, several of whom were commissioned by Rothschild to contribute to Novitates Zoologicae and other publications.
