Check the 'Source' instruction to be sure that you are looking at the correct source(s) of information on the resource
If data on the resource and data as the element in the record are:
- PoR/PaE–check the Data Entry instructions:
  - data for this element must be Recorded as instructed but 1.8: make sure the data is recorded as instructed
- PoR/AaE–check the Core instructions:
  - data for this element is CoreIf:
    - it is ok if the element is missing as long as the related element is present
    - but if the related, core element is also missing, and cannot be added, then add this element
    - also consider adding this element if it helps to explain 'supplied' data in the related, core element
- AoR/PaE–check the Source instructions again:
  - since the Source for this element is or includes 'Any', accept the data, but only if it seems applicable
- AoR/AaE–go to the next element:
  - but be sure to check the resource carefully, if the data for the element is Core, or if the data is important for differentiating the resource from a similar resource

General Notes:

data for this element is only needed if available, and if no date of publication or distribution is identified, but it is useful to add the copyright date, if it has been used to supply the publication date
it is ok to enter a copyright date that is the same as the publication date, if you choose to do so
enter dates 'as found', so enter Roman numerals as found (e.g., “MCMX”) if you are following LC practice (1.8.2 Alternative); otherwise substitute Arabic numbers
if both the original and a renewal copyright date have been provided on a resource, then the last two paragraphs at 2.11.1.3 tell us to record only the latest date; I recommend also adding the renewal statement as a Note on Copyright Date, e.g., “Copyright 1934, copyright renewed 1962”)

MARC:

I2 must be '4' for copyright information
make sure that the subfield is '$c' not '$a'
use the symbols © or (p), or spell out the words 'copyright' or 'phonogram' instead of using the abbreviations 'c' or 'p'
264_4 does not end in a period
