ndicated by three stars (* * *); of other matter by three
dots (...). The phraseology, spelling, and punctuation of the title
are exactly copied; but capitals are given only to proper names and
adjectives, and initial words of sentences. Any additions needed to make
the title clear are supplied and enclosed by brackets.

After the titles, are given in order: the place of publication; the year;
the year of copyright, if different, in brackets; the edition; the number
of volumes, or of pages if in only one volume; the illustrations, maps,
plates, or portraits; and the size nearest in the arbitrary scale,
regardless of the fold of the sheet. This scale gives the heights in
decimeters. Square and oblong books have the size prefixed by _sq_. or
_ob_. Books 1 decimeter high are called 32 deg.; 1.5 deci., 16 deg.; 2 deci.,
12 deg.; 2.5 deci., 8 deg.; 3 deci., 4 deg.; and all others are marked simply by the
nearest height, i.e. a book marked 4 is between 3.5 and 4.5 decimeters
high. In books having more than one pagination the number of pages is
indicated by giving the last number of each pagination connected by a +;
an added + indicates additional matter unpaged.

These imprint entries give the facts regardless of the title page, and
are left blank only when they can be ascertained neither from the book
itself or other sources.

The contents of volumes are given when on title pages, or when necessary
to properly identify the volume, but no analysis is attempted. Necessary
notes are given at the bottom of the subject card after the imprint
entries.

Duplicates are simply marked copy 2, copy 3, etc., and bear the same
class and book number, but editions of the same book distinct in
character are catalogued separately.

In all the catalogues, books are entered under the _surnames_ of authors
when known; under the _initials_ of author's names, when these only
appear, the last initial being put first; under the _pseudonyms_ of the
writers, when the real names are not ascertained; under the names
of _editors_ of collections; under the names of _countries, cities,
societies,_ or other _bodies_ which are responsible for their
publication; under the _first word_ not an article of the titles of
periodicals and of anonymous books the names of whose authors are not
ascertained. _Commentaries_ with the text, and _translations_ are
entered under the heading of the original work, but commentaries without
the text are entered under the n
