THE BRACKET
Brackets are used in pairs, like the parentheses. In Job composition either brackets or parentheses may be used, as suits the fancy or is convenient. In descriptive text matter, however, brackets should not be used where parentheses are clearly indicated.
Rules for the Use of the Bracket
1. To enclose words or phrases which are entirely independent of the rest of the sentence.
The enclosed words are usually comments, queries, corrections, criticisms, or directions inserted by some person other than the original writer or speaker.
2. To enclose passages of doubtful authenticity in reprints of early manuscripts, special amendments to bills under legislative consideration, or any other portions of a text which need peculiar identification.
3. In legal or ecclesiastical papers to indicate numerical words which may have to be changed, or to indicate where details are to be supplied.
