The title is to be an exact transcript of the title-page, neither
amended, translated, nor in any way altered, except that mottoes,
titles of authors, repetitious, and matter of any kind not essential,
are to be _omitted_. Where great accuracy is desirable, omissions
are to be indicated by three dots (...). The titles of books
especially valuable for antiquity or rarity may be given in full,
with all practicable precision. The phraseology and spelling, but not
necessarily the punctuation, of the title are to be exactly copied. (3a
Any _additions_ needed to make the title clear are to be supplied and
inclosed by brackets. (3b
