Both Jones and Cole were concerned that these collections would encourage students to simply copy examples of ornament, rather than be inspired to examine the underlying decorative principles behind the objects. Furthermore, the location of the collections in London made it difficult for students at the provincial Schools of Design to gain access to them. These two factors would undoubtedly have been significant catalysts in motivating Jones to publish, in 1856, what is possibly his longest-lasting legacy: his seminal design sourcebook, "The Grammar of Ornament".
