I have noticed these too, and I think in many cases people are simply getting confused about the punctuation. Which is honestly easy to do.
As I said, Wilson, Pete. $t Works. $k Selections. $f 2019 implies that there is only 1 selection of Pete’s Works, but more than 1 expression of that sole selection. That situation doesn’t come up much.
Thanks, Jessica and Steve. I should have acknowledged that the $f and the parenthetical date in $k technically serve different, non-conflicting purposes, but I am guessing that the $f is rarely used in a “Selections” context with the intent of naming an expression. I think when it is used in a “Selections” heading, it is usually meant (incorrectly now) to identify a particular work—a particular set of selections. If I’m off base on that I’d love to be corrected.
There are more name-title records than I expected in the NAF with a year qualifier of 2018 or 2019 in an $f subfield. I’m guessing that they are intended as work qualifiers rather than expression qualifiers, and many catalogers just haven’t adjusted. I figured it’s either that or there’s less consensus than I thought. Or maybe sometimes the dates really are intended to specify an expression of a base “Selections” work.
That is true, now, under RDA, but a lot of those Wilson, Pete. $t Works. $k Selections. $f 2019 style headings were created in AACR2. They were then programmatically recoded as RDA. For Wilson, Pete. $t Works. $k Selections. $f 2019 to make sense as an expression heading there would have to be only 1 selection of Pete’s works, but multiple expressions of that 1 selection such that you would need the date to distinguish them.
The first form (date in $f) is an AAP for an Expression. The second form (parenthetical date in $k) is an AAP for a Work.
I got curious about something and looked through the NAF a little at name-title headings that include “Selections.”
I was surprised at how many recently created authorities use this form:
Wilson, Pete. $t Works. $k Selections. $f 2019
Wilson, Pete. $t Works. $k Selections (2019)
I thought the question of whether to qualify with an $f subfield or just enclose the qualifier in parentheses in the $k had been fully decided, or as fully as such questions can ever be decided. Is that correct, or is there still a live difference of opinion among the “experts?”
