This particular issue was not dealt with in Module 6 but there is a recent FAQ on the NACO website that deals with it:; then go to the bullet point

Working with “Undifferentiated” conventional collective title work and expression authority records: FAQ


Or the direct link is here.



The FAQ was posted before the “Feasibility study” for deemphasizing conventional collective titles with “Selections” (see FN 3 in the FAQ). The outcomes of that study have not been published nor have policies been made yet. The FAQ will be revised when policies have been made on this issue.


Meanwhile, the main point was that differentiation between various “selections” of an author are made at the work level, so generally speaking we’d expect some sort of qualifier after the word “Selections” if there are more than one collection of a person’s selected works. But the trend is to simply name the collection by using the name of the collection found on the manifestation.


Note: the Feasibility study only applies to conventional collective titles (and as I said, final decisions on policy have not been made). Selections from an individual work will continue to be treated as described in the FAQ.

Subject: Establishing an expression-level name/title series


Dear Collective Wisdom,


When one wants to establish an expression-level name/title series for (Works. Selections), where should one turn to for examples of PCC’s best practices? I looked closely in the NACO training modules 6 (works and expressions) and 6s (series) and Session 6a-b of the more elaborate “NACO Series Training” but could not find an example similar to the following:

The record looked fine to me, until I saw this:

Without the books in hand, It is difficult to know what 2003, 2007, and 2012 represent exactly. Different expressions or simply manifestations? How could one tell if the intellectual contents, i.e., “Der Ling, Princess. Works. Selections” is NOT the same? Well, let us just suppose they are different compilations. Would be much better to qualify “Selections” first?


Der Ling, Princess. $t Work. $k Selections (2003). $l Chinese

Der Ling, Princess. $t Work. $k Selections (2007). $l Chinese

Der Ling, Princess. $t Work. $k Selections (2012). $l Chinese


But if they are indeed the same compilations in Chinese translation--no changes or revisions, then, $f 2003, $f 2007, and $f 2012 seem superfluous to me, unless one wants to treat them as dates of manifestation. At this point, however, we are not supposed to establish manifestation-level authority records, are we?!


Best regards,
