You might find (LC-PCC PS for 2.8.6.6 <http://access.rdatoolkit.org/2.8.6.6.html> ) helpful.
I believe that PS would have you do: 264 _1 . $c[2005] 264 _4 $cC2005 DtSt = t Dates = 2005, 2005 Basically, LC suggests that you supply a date if known or probable, guess one if at all possible, using a copyright date, distribution date, first printing date, or some other method, and make a broad guess if that is all you can do, as per 1.9.2 <http://access.rdatoolkit.org/1.9.2.html> . IOW, do everything you can to guess a publication date, because if you cannot put *something* down for that element and have to enter [date of publication not identified], then, as far as I can see, you will need to do this: 264 _1 . $c [date of publication not identified] 264 _2 . $c [date of distribution not identified] 264 _3 . $c [date of manufacture not identified] DtSt = n Dates = uuuu, uuuu This basically takes us way back to the pre-AACR days when we could do [n.d.] (no date), but then makes that option so unpleasant that we will stick to the AACR principle of always putting down a date of publication, no matter how wild our guess has to be. I may be way off base about this, so I would very much like to hear what the collective wisdom has to say about my interpretation of the 'Core' instructions for Date of Distribution (2.9.6 <http://access.rdatoolkit.org/2.9.6.html> ) and Date of Manufacture (2.10.6 <http://access.rdatoolkit.org/2.10.6.html> ); i.e.: * Date of distribution is a core element for a resource in a published form if the date of publication is not identified.-- therefore if [date of publication not identified], and you have no date of distribution either, then enter [date of distribution not identified], for a single-part resource (2.9.6.6 <http://access.rdatoolkit.org/2.9.6.6.html> ) * Date of manufacture is a core element for a resource in a published form if neither the date of publication, the date of distribution, nor the copyright date is identified.--therefore if [date of publication not identified], and [date of distribution not identified], and you have no date of manufacture either, then enter [date of manufacture not identified] , for a single-part resource (2.10.6.6 <http://access.rdatoolkit.org/2.10.6.6.html> ) Deborah - - - Deborah Fritz TMQ, Inc. debo...@marcofquality.com www.marcofquality.com -----Original Message----- From: Resource Description and Access / Resource Description and Access [mailto:RDA-L@LISTSERV.LAC-BAC.GC.CA] On Behalf Of Snow, Karen Sent: Monday, October 22, 2012 10:02 AM To: RDA-L@LISTSERV.LAC-BAC.GC.CA Subject: [RDA-L] "Date of publication not identified" & DtSt, Dates I've done a little searching and can't find the answer, so I am hoping the collective wisdom can help me out... If you use [date of publication not identified] in 264_1 $c and you have a copyright date in 264_4 (let's say 2005), how would this look in DtSt and Dates fixed fields? DtSt = t Dates = uuuu, 2005 ?????
