But this completeness is not usually sought even in large libraries. Such references {37} are also undeniably a help in finding books. But they increase the bulk and the cost of a catalogue so much and are comparatively of so little use that ordinary libraries must content themselves with a selection, though the best-made selection is certain to occasion complaints that the really useful ones have been omitted and the least important made. The chief classes of necessary references of this sort are—

It may be thought that an excessive number of references is recommended, but it is plain that wherever there can be a reasonable doubt among cataloguers under what head a book ought to be entered, it should have at least a reference under each head. The object of an author-catalogue is to enable one to find the book; if that object is not attained the book might as well not be catalogued at all.
