(§ [3].) From joint authors (after the first) to the first.
(§ [5].) From the præses to the respondent or defendant of a thesis, or vice versâ.
(§ [6].) From pseudonyms, initials, and part of names.
(§§ [7], [8].) From important illustrators when not important enough for an entry.
(§ [12].) From commentators who are not entitled to an entry, if the commentary preponderates or for any reason is likely to be looked for under the commentator’s name. Where the line of omission shall be drawn depends on the fullness of the catalogue.

(§ [18].) From the names of reporters, translators, and editors of anonymous works and of works not anonymous which are commonly known by the name of their editors or translators.

(§ [19] a.) From the foreign form of names of sovereigns, whenever they are likely to be looked for under that form.
(§ [19] b, c.) From the family name of persons canonized, and of friars who drop the family name on entering their order.
