   This is the point of greatest ambiguity in LCRI 22.3A. It does state
"(The form found in the chief source of a person's thesis is taken into
account when choosing the form to be used in the heading)." The problem
with that is that it generally true that the thesis form is going to be
"fuller" (see below) or more detailed than the form on publications, *and*
the author did not have freedom of choice in picking the form on the
thesis.

   The ambiguity can be resolved by recognizing that the parenthetical
statement above is applied in the context of the statement "choose as the
AACR2 form the form found in 80% of the author's works." So, the
parenthetical statement is referring to making a choice based on 80% and
no other basis for choice ("fullness" is in the paragraph following the
instructions for making the 80% determination).

   The definition of "fullness" is commonly misunderstood. It is explained
as follows in the same LCRI, to wit: "When determining the fullest form
... make no distinction between initials and forenames." A poor example
fails to illustrate that "Russell, Marc J." is equal in fullness to
"Russell, Marc James" [the date does not enter the "fullness"
determination]. So, if there is not 80% predomination and "Russell, Marc
J." is not the only form per paragraph "1)" of the LCRI, you could
establish the heading as: "Russell, Marc J. $q (Marc James), $d 1975- ".
