"Books differ in manifold diversity, in matter and in manner, in infinite variety and in complicated relations. They retrace worn paths; they blaze new trails; they run wild over frequented fields or in regions hitherto unexplored; they climb the heights; they plumb the deeps; they delve; they discover bonanza mines; they take winged flight into the empyrean. How can the librarian bring such wayward creatures into the bonds of organization? How shall he bind these intertwining vines to the trellis of classification?"
- H.E. Bliss (1939) "The problems of classification for libraries"
Preach, H.E. Bliss, preach.
