Revising an existing authorized access point (AAP) creates additional work for bibliographic file maintenance (BFM); therefore, modifying an existing AAP simply to add a birth or death date, when they are absent, is really a last-resort option. Please note that adding a date is allowed in some circumstances (see point 6, below).

When an AAP being established conflicts with another AAP already established in Canadiana for another person, and a date is available for the person already established in Canadiana, but not for the new person, it is therefore preferable to make the new AAP unique by using another method allowed by RDA to distinguish AAPs, such as, (Profession/occupation), (Author of [Title of work]), etc., rather than modifying the existing AAP.

The LAC-BAnQ Policy Statement for RDA 9.19.1.1 states, however: “If there are no additions readily available to differentiate the access point in the new authority record, make an addition to the existing authorized access point”.

When revising existing authority records, the date of birth, if known, must be recorded in field 046 $f, even if not included as part of the access point. (Cf. Name authority manual, field 046, 2nd paragraph).
