Where do you start?
Where on a book do you usually find publication and/or copyright date information?

What are you looking for?
What is the first date to look for when matching?
Publication date
What else?
If there is no publication date, what do you look for next?

How can you tell?
How do you know the difference between a copyright date and a publication date?
Copyright symbol (©) or the word copyright in front of the date
Copyright dates
Your book has a copyright date of 2010 for the text and a copyright date of 2012 for the cover illustration. Which do you use for matching?

Unless…
There is evidence this is a new edition
Illustration copyright date may be used as an implied publication date and will appear in the bibliographic record in brackets: [2012]
Multiple copyright dates
Your book has no publication date, but has: ©2005, 2007, 2009. Which copyright date do you use?
Copyright date 2009
Unless…copyright renewal dates
Your book has: ©1945, ©renewed 1992. Which date do you use?©1945. For works copyrighted before

1977, use the copyright renewal date
Future dates
You’ve received a newly-published book by a best-selling author. The t. p. verso has ©2015. Is it okay to have a future date in a bibliographic record?
Yes
Printing dates
Your book has a publication date of 2012 and a printing date of 2013. Which date do you use for matching?
Publication date. Printing dates are usually ignored
Unless…
Your book has no publication or copyright date, but has a first printing date of 2013

Or…
A printing statement implies a new publication, even if there is no publication date. Often seen with Scholastic: First Scholastic printing, March 2005 (usually on the t.p. verso)

Cataloger-supplied dates (AACR)Dates will be in brackets, and may be
followed by a question mark [2012] Implied publication date based on available information,
i.e, printing date [2012?] Estimated date—cataloger made their best guess [199-] Publication in the 1990s, not sure what year [19--?] Estimated publication sometime in the 1900s
MARC coding for dates -- AACR
MARC tag 260, subfield c If publication date and copyright date are the same, record
only the publication date 260 $aNew York :$bOxford University Press,$c2012.
If publication date and copyright date are different, will often see both 260 $aNew York :$bOxford University Press,$c2012,
c2010.Copyright date is preceded by lower case c
Implied or estimated dates are in brackets 260 $aZion, IL :$bZion Historical Society,$c[2005?]
MARC coding for dates -- RDA MARC tag 264, subfield c Publication and copyright dates are recorded in separate fields
264 1 $aChicago :$bLion Publishers,$c2012. 264 4 $c©2010
Copyright date is preceded by copyright symbol or the word copyright (transcribe from item)
No ending punctuation Publication date is a core element in RDA. If no publication date
is present, but there is a copyright date, the copyright date is recorded in brackets as an implied publication date 264 1 $aChicago :$bLion Publishers,$c[2012] 264 4 $c©2012
MARC coding for dates – Fixed fields Coded based on the dates in 260 or 264 subfield c Type of Date (Polaris) / DtSt (OCLC)
Code that categorizes type of date, i.e., s for single date, or t for publication and copyright date
Date 1 and Date 2 (Polaris) / Dates (OCLC)Enter publication date in first date boxEnter copyright date in second date box
Check these when editing records – dates in the fixed field affect searching!
Make sure the fixed field and the 260 or 264 match
