Attribution, Citation, and Copyright: Documenting Sources

General Guidelines for Citing Resources for Digital Projects

All elements must be documented. Some digital resources have specific instructions for use and attribution.  Otherwise do your best to capture the most essential descriptive elements, such as:

  • Creator
  • Title (or brief description in square brackets)
  • Publication information (specific page or resource where you found it, not Google)
  • Date (creation or publication, if available)
  • Access/Retrieval Date
  • URL

In-Text citations for images should be listed as a note and should  include descriptive text (see Images tab for more information).

Online Multimedia (including streaming video)

CMOS 17, 14.265 and  CM0S 17, 14.267-268 addresses online video and film recordings. Some important information addressed in this section includes:

  • Citing the original source, if a digital version of the source is found  (also see
  • Indicating the source type of the original (i.e., 35 mm film) and the format found (i.e., DVD, MPEG, YouTube video)
  • Including duration or length
  • If no date can be determined from the source, include the date the material was accessed.
