Concise AACR2: 30. Introduction

In making a heading for a person, take the following three steps.
First, choose the name that will be the basis for the heading. Most persons are only known by one name. In some cases, however, a person is identified by two or more names or by two or more forms of the same name. For example, the same woman is known as Jacqueline Kenndy and Jacqueline Onassis , and the same man is known as Herblock and Herbert Block.
Second, decide which part of the chosen name should be the first word in the heading (the filing element). Again, in the majority of cases this is simply the surname.1 In some cases, however, the choice is not so obvious. For example, should it be Gaulle, Charles de or De Gaulle, Charles?
Third, make references from different names for the same person or from different parts of the chosen name. For example, you should refer from Geisel, Theodore to Seuss, Dr:; from Clay, Cassius to Ali, Muhanmmad; and from Da vinci, Leonardo and Vinci, Leonardo da to Leonardo, da Vinci.
Rules 31–44 deal with the first two steps and with their associated problems. Rule 63 deals with the third.
1.Surname, as used in these rules, includes any name used as a family name.
