 Encyclopaedic repetition with an Aristotelian slant is being displaced by original compilation in which deference to authority plays no part whatever. Individual erudition is being dumped in favour of collective research. Conservation of traditional knowledge is being discarded in the interest of a new, functional realization of natural history, which demands that legenda—things worth reading—be supplanted by materials which will form the basis of a thoroughgoing attempt to improve the material conditions of the human race. (Rees, in OFB XI, xlii)
