Box 139Options for date of publication

It is not NLM policy, but the date of publication may follow the author(s) (or title and type of medium if there is no author) in the list of references when the name-year system of in-text references is used.

  • Use the date of the earliest messages or of copyright if there is no publication date
  • Keep the hyphen following the date when the blog is open
  • Include both the beginning and ending years if a blog is closed
  • Keep any square brackets surrounding a date
  • Place the date unknown after the author(s) (or title and type of medium if there is no author)
  • End date information with a period
  • Leave the date of citation in its usual location
