XXXVIII. Maps, Charts, Engravings and Music, (except when published
in volumes,) are not to be included in catalogues of Books. Separate
catalogues of these should be constructed upon the general principles
of the preceding rules.
(1.) In cataloguing ~Maps and Charts~, the full title is to be given,
including the names of surveyors, compilers, engravers, publishers,
&c.; date and place of publication; and number of sheets composing
the map. Each edition is to be separately recorded, and the separate
title of each sheet, when it varies from the general title. The
titles of sub-sketches are to be introduced at the close of the
main title, within brackets, and to be given in full, including
authorship, scale and size.
(2.) The scale is to be given in all cases. When not stated on the
map, it is, if possible, to be derived from it.
(3.) The size of the map, within the _neat-line_ of the border, is to
be given in inches and tenths. When a map has no printed border, the
measure of the limits of printed surface is to be given.
(4.) The price, if stated on the map, should be copied.
(5.) All important peculiarities of copy, such as the kind of paper,
and whether backed, folded, bound, on rollers, &c., should be
mentioned in a note.
The titles thus prepared are to be arranged under the names of the
countries, or divisions of the earth's surface delineated in the
maps; and these names are to be disposed in alphabetical order, with
the cross-references necessary to facilitate research.
(6.) ~Engravings~ are to be recorded under the names of the
engravers, with cross-references from those of the painters or
designers. The date, and the name of the publisher, if found upon the
print, should also be given. The size of the print, in inches and
tenths, should also be stated. If the copy be an artist's proof, or a
remarkably good impression of a valuable engraving, the fact should
be stated in a note.
(7.) ~Music~ is to be entered under the name of the composer. If the
work have a distinctive title, there should be a cross-reference from
that.
