It seems like all we really need to do in the 670 $b is give the facts clearly and unambiguously. We aren’t transcribing text—we’re getting and giving information. It may be pretty clear to most that the date 1954-08-03 (from the 184.108.40.206 example) means August 3 rather than March 8, but I’d spell that out just to make sure. I see no value in attempting to record the exact text as found.
Dear PCCLIST readers,
Thanks to Mark Ehlert and John Hostage for their responses (my apologies for confusion over EDTF and ISO 8601). And for mentioning RDA 8.12 Source Data Found, whose LCC-PC PS refers to DCM Z1 670. I think the instruction there should apply to dates in subfield a but not in subfield b. Here's why.
There is no question about instructions to record the date on which data is found in a particular source, in subfield a of field 670: Month spelled out, followed by day and year. But in subfield b, where one records the data found, the intention of RDA is to record the data as found rather than adjust it to the Month, day, year format. You do that in field 046, but not in field 670.
220.127.116.11 has an example which illustrates this point. The birth and death dates were found to be in YYYY-MM-DD format:
Catalogue Bn-Opale plus, via WWW, March 11, 2009. Authorized access point: Colette (1873–1954); variant access points: Willy, Colette (1873–1954); Colette, Gabrielle Sidonie (1873–1954); Colette, Sidonie Gabrielle (1873–1954); nationality: France; language: French; gender: female; roles: author, performer; birth date: 1873–01–28; death date: 1954–08–03
RDA 18.104.22.168 Recording Source Consulted also has an example demonstrating that the intent of RDA was not to rearrange a date statement:
