The presence of a recorded date of expression means the record is no longer a “generic” record covering all English language expressions of a given work. The record applies only to the expression that was created in that year (or first published in that year). Different expressions are created in different years, so by recording a specific year you are pinning the record down to a specific expression.


Bizarrely, there is no evidence for the 046 date 1927 in n  85022980, but it does appear from an OCLC search that an English language expression of Rølvaag’s I de dage was indeed published in 1927, so this record would correspond to that particular expression, not another (perhaps there is only one English language expression of this work, but if there are more than one, n  85022980 can only apply to the expression first created in 1927).


Randomly looking at a few of the other examples you give, most of them don’t seem to have any evidence for the 046 field data either.


In my opinion if any expression-related attribute aside from language (377) is recorded in an authority record, that takes the record out of the realm of “generic” language expression and it becomes a record for a specific expression, the one that corresponds to whatever attributes have been recorded (in these cases, date of first creation of the expression). So my response to Mark’s question would be “No, these records should not be treated as describing a generic expression, they describe a specific expression.” But I have no idea what the LC catalogers were thinking when they enhanced these records with 046 fields.

Subject: Date of expression in DLC authority records?


I've come across several authority records exclusively sourced and edited by DLC (per the 040 field) for English translations that include 046 dates that specify the date of expression.  The heading itself is generic following LC-PCC PS 6.27.3--Name. Title. English--but the record is made specific with that added date.  Many, but not all, of the records were last edited in February-March 2013, which point to the Phase 2 RDA Authorities project.  However, none of the 1xx/4xx headings use the $f, which I presume would be the source for the automated population of the 046 field.  Several 046s also don't match the source dates in the 670s; manual intervention is implied there.


Random examples by LCCN:
n  90636367
no 97019257
n  80148532
n 2012079161
n 2013001274
n 2013037659
n 2013062190

So a question of practice for those of us who aren't LC: Should these records be treated as generic expression?  Or specific expression?  I presume the 046s aren't meant to act as the start date(!) for a collection of English expressions covered by a single record.  I have one translation record in front of me I'd like to edit, but don't know how to go about enhancing it, if at all (n  85022980, last touched in September 2013).
