If a personal name heading conflicts with another heading, resolve the conflict as follows, in this order of preference:

1. Add to the heading being established

a. the full form of a name represented by an initial or abbreviation in the form chosen for the heading if the full form is available in the item being cataloged (22.18);

Example A

b. the date (22.17) other than a "flourished" or "century" date; do not go beyond making a routine telephone call to a place within the continental U.S. or searching the catalogers' reference collection to determine the date;

Example B

Note: If both the full form represented by an initial and a date are available, add both.

c. a term of address, etc., that appears with the name in a prominent source (cf. 0.8) in items by the person or with the name in headings in reference sources (22.19B). (For pre-20th century persons, see LCRI 22.19);

Example C

Note: If either the full form of the name represented in the heading by an initial or a date becomes available later (or both become available), do not change the existing heading just to replace the term of address, etc.

d. a forename or surname or the initials of a forename or surname not represented by an initial in the form of name chosen for the heading;

Example D

Note: If the full form of a name represented in the heading by an initial or a date or a term of address, etc., becomes available later, do not change the existing heading just to replace the unused forename or unused surname.

e. a full forename when the forename chosen for the heading is a nickname;

Example E

Note: If the full form of name represented in the heading by an initial or a date or a term of address, etc., becomes available, do not change the existing heading just to replace the unused full forename.

f. a "flourished" date (22.17);

Note: 1) Do not add "flourished" dates to headings for persons living in the twentieth century even if the heading conflicts. 2) "Flourished" dates acceptable for addition to headings normally express a span of years of activity. A single year after "fl." may be used only in exceptional cases, as when a reference source itself designates the date in this way or there is one publication or other event in the person's life known to be the single or at least primary basis for a single year.

g. a century date (22.17).

Note: Do not add a "century" date to persons living in the twentieth century even if the heading conflict.

2. Change the established heading according to the order of preference given in 1. above.

3. Apply 22.20.

Note: If the full form of a name represented by an initial in the heading or a date or a term of address, etc., becomes available later for one of these names, establish this name separately. (Do not establish one of these names separately if only an unused forename or unused forename initial or unused surname or unused full forename becomes available later.)
