Per LC PCC PS 2.8.6.6 adding the copyright 264 _4 field is optional as long as 264 _1 doesn't have [date of publication not identified]. LC training's best practice is to supply an inferred date instead of [date of publication not identified] since when the "not identified" filler is used, RDA requires the additional transcription of a distributor or manufacturer 264 if either has an explicit date, or, lacking distribution or manufacturer dates, as a last resort, the copyright date. Optionally you could create additional 264s for distributor, manufacturer, and copyright date even if you have an inferred date of publication, but I do not recommend the option to my trainees. It seems to me the whole point of providing bracketed inferred data in 264 _1 is so you don't have to create additional 264s. I'm aware that the copyright date might be considered important by rare book/special collections cataloging, but I don't think the rare book perspective should drive general cataloging practices.

If the copyright date is for the year following the year in which the publication is received, supply a date of publication that corresponds to the copyright date." And this is a carryover from an LCRI that said, basically, the same thing. So, I would recommend: 264 #1 $c [2014] 264 #4 $c (c)2014 Adding the Copyright Date in this case, would help to explain the choice of the supplied Date of Publication Deborah - - - - - - - - Deborah Fritz TMQ, Inc.

Regards -----Original Message----- From: Resource Description and Access / Resource Description and Access [mailto:[email protected]] On Behalf Of Goldfarb, Kathie Sent: 28 March 2013 13:48 The book I have in hand lists a copyright date of 2014. Should the 264 be: 264 1 ...$c [2013] 264 4 4a @2014 Or 264 1 $c [2014] No 264 4 I am leaning toward the second, since many libraries may receive this book in 2014, and the first option might be confusing, since they would not know for a fact that some were distributed in 2013.
