The index is generally placed at the end of the volume, and set in letter
two sizes less than that of the work. It is always begun upon an uneven
page. In setting an index, the subject-line should not be indented; but,
if the article make more than one line, all but the first should be
indented an em.
In preparing the copy of an index, care should be taken that the
subject-words are arranged alphabetically, as the compositor will not
transpose his matter afterward without remuneration.
Where several index-figures are used in succession, a comma is put after
each folio; but, to save figures and commas, the succession of the former
is noted by putting a dash between the first and last figures: thus,
4-8. Again, if an article has been collected from two pages, the folio
of the second is supplied by _sq._, or _sequente_, and by _sqq._, or
_sequientibus_, when an article is touched upon in succeeding pages. A
full-point is not put after the last figures, because it is thought that
their standing at the end of the line is a sufficient stop. Neither is
a comma or a full-point placed to the last word of an article in a wide
measure and open matter with leaders; but it is proper to use a comma at
the end of every article where the figures are put close to the matter,
instead of running them to the end of the line.
