NOTE. - These figures are the results of tables made out year by year, like the one constituting Appendix VI for 1869.

CLASS XVIII includes Mechanics, Military and Naval Arts, Agriculture, Domestic Arts, etc.

CLASS XXI embraces all such pamphlet volumes as may have been received from time to time, and are generally too heterogeneous in their make-up to be
classed otherwise than by themselves. The figures of this class under "Prince Library" denote MS. volumes.

The subdivisions of classes are kept in ranges by themselves, so that for purposes of enumeration or learning percentage of use, it is practicable at any
time to get exact figures upon the subdivisions; as also upon such points as Biography, Travel, and Voyages, etc., by summing the results of the ranges devoted
to them in the several alcoves.

NOTE.The above figures of the three special collections exhibit them as when received in the Public Library and assigned to our shelves. There have
been since then some small additions to them, chiefly from continuations of serials, but such accessions are counted in the classes of the General Library, though
the books are located with the special collection.
