22.18A.

For names that conflict, see 22.18-22.20.

For references, apply the provisions of LCRI 26.

Apply the optional provision. This means adding within parentheses the full form of an initial or abbreviation used in the heading when the full form is known with certainty. (In some cases of doubt, do not add the full form.) Do not search solely to discover this information if there is no conflict.

When adding the full form, observe the following guidelines:

1. If the initial occurs in the forename portion of the surname-forename heading, give in the parenthetical addition not only the full form but also the other forenames that appear in the forename portion of the heading. However, do not include a particle or prefix that appears in the forename potion. Place the parenthetical addition directly after the forename portion and before any other addition (e.g., date, title).

Example A

2. If the initial occurs in the name entered as a given name, etc., give in the parenthetical addition all the names that appear in the heading. Place the parenthetical addition directly after the given name and before any other addition (e.g., date, title).

Example B

3. For names that are represented in the heading by an abbreviation rather than an initial (cf. LCRI 22.1B), give in the parenthetical addition the full names for the particular person.

Example C

Exceptions:

1. Do not apply 22.18A to a name in which the letters of the forename initials used in the heading differ from the letters used in the full forename.

Example D

2. Do not apply 22.18A to a heading for a married woman that consists of her husband’s surname and initial(s).

Example E

3. Do not add the fuller form to an existing heading falling into either of the following categories:

a. The name authority record for it has already been coded "AACR2" or "AACR2 compatible" (including in either case those labeled "preliminary" 008 byte 33 = d).

b. The heading is represented by an access point on an existing bibliographic record in the catalog (i.e., the file against which the cataloging and searching is done) and is otherwise in accord with current policy.
