Blogs often omit giving the date the blog began. If no beginning date is found, use the date of the earliest message posted (usually found under Archive) and place it in square brackets.

When a reference to a blog posting is included in a reference list, the author must provide written permission to the publisher from the cited person (if living) or from the cited organization. The permission should be a statement in an "Acknowledgments" or a "Notes" section that follows the text of an article or is placed at the end of a book's main text. Such statements may include additional details, such as the reason for the posting.
