Theodore Wesley Koch,
The Library Assistant's Manual
“ The moral to be pointed out is that the catalog must be good as a first requisite to a library. In the words of the old comparison, the catalog is the key to the otherwise hidden material buried in books. In a library of any size, the best desk attendant in the world is almost helpless, or at best constantly handicapped, without a convenient and rational classification of the volumes of the collection and the bibliographical aid of a catalogue. The born bibliographer is as rare as the born teacher or poet. ”
