_Ex._ For a book “by J. B. Far...,” or “by L. M. P.,” or “by Ddg.,”
or “by —lsd—,” the entry is to be made under «Far...», J. B., «P.»,
L. M., «Ddg.», «—lsd—». If the last initials are evidently, from the
style of printing, those of a title, the entry will be under the
initial preceding them; thus for books “by B. F., _D.D._,” or “by M.
P. R., _Gent._,” or “by X. Y. Z., _D.D._,” the entry is to be made
under «F.», B., _D.D._, and «R.», M. P., _Gent._, and «Z.», X. Y.,
_D.D._ In such case it is safest to have also a reference from the
last initial to the one chosen, as «D.», X. Y. Z. D. _See_ «Z.», X.
Y., _D.D._ It is often well to make a reference from the first word
(title-reference). This mode of entry ensures the easy finding of a
particular book and brings together all of an author’s works in which
the same letters are used, and sometimes leads to the discovery of a
real name.
Even mere printer’s marks, as *** or ..., or !!!, unaccompanied by
any letters, though they can not be considered as names, may be used
as headings for a reference {34} for the sake of bringing together
all the works of an author using them; but each work should also have
title entry if anonymous.
