Book number, fourth term in classification number
The book number follows the colon.
In the case of annual or periodical publications, the date is used as the book
number, as :906. For a volumed series, the volume number is used, as :8. For a
numbered series, the number is used, as :8. General publications and similar classes
are arranged in alphabetical order under the most significant words of their titles,
or under their subjects, the book numbers being assigned from the 2-figure Cutter
Author table, as :B39, in which case B39 stands for Beet sugar, the distinctive word
of the title.
In the Checklist, individual book numbers are given for everything arranged by
book numbers taken from the Cutter Author table, except for separates, which are
not entered at all, and for which the arrangement is only indicated, as :(CT). Individual
book numbers are not given in certain series arranged by dates or by numbers,
but in every such case the arrangement is indicated, as :(dates), or :(v. nos.), or :(nos.).
The superior letter (a) always designates "separates," that is, excerpts from the
publication bearing the same notation without the (a). These separates are arranged
in classes by themselves, immediately following the series from which they are taken.
The superior figures (1-9) are used to differentiate between two publications which
may of necessity be assigned the same symbol in the alphabetical classification,
and also to distinguish between the various editions of the same serial or numbered
Examples of complete classification numbers
The following examples of complete call numbers illustrate the principles outlined
in the foregoing paragraphs on classification:
W1.1:909 2 War Department, Secretary, Annual reports, 1909, v. 2.
LC2.2:P84 = Library of Congress, Bibliography Division, General publication
entitled List of books, with references to periodicals, relating to
postal savings banks.
A19.3:56 2 = Agriculture Department, Plant Industry Bureau, Bulletin 56, 2d
A29.6:370= Agriculture Department, Weather Bureau, Monthly weather
review, v. 37, no. 10.
These examples-are sufficient to show how expansive this system is, yet how concise
in its application.
Maps, Charts, and Specifications
Attention is called to the fact that in case of certain issuing offices which are large
publishers of Government charts, maps, and specifications, no attempt is made in
this Checklist to enter such publications. In all instances, however, where this happens,
the classification of the series is clearly indicated, showing how the class would
be bpoknimbered. This refers to such large classes as Geological Survey Topographic
sheets (119.12:), Post route maps (Pll.5:), Hydrographic Office Charts (N6.18:),
Northern and Northwestern Lakes Survey Charts (W33.6:-W33.8:), Quartermaster's
Department Specifications (W39.11:), etc.
CONGRESSIONAL NOTATION FOLLOWING ENTRIES FOR BUREAU EDITIONS
When a document appears both in a bureau edition and as a Congressional document,
the bureau edition is entered in the Checklist and the serial number and Con,essi&nil
document number are both added thus "[2309-269]," the first being the
Relial number and the second the document number in the Congressional set.
