When you cannot locate the article using the date cited by the author, try searching a newspaper database using the article's title/author information. The news coverage date for an event may post-date the actual event because of publication delays.
Some content is not included in the electronic version of newspapers. Some examples of excluded content are: freelance writers' articles in the event the writer will not relinquish rights for the content to be reused in an electronic edition; special editorials or Op-Ed pieces written by non-newspaper staff (again, the newspaper does not have default rights to this content); and classified advertisements. The Bluebook Rule 16.6 details the citation format for newspaper editiorials.
Some newspapers are moving to electronic editions only, while others have much more content on their websites than in their print editions. For example, an article may appear in the Washington Post blog and never appear in the print version of the newspaper. Citation to the more stable, print versions of newspapers is only possible when the content being referred to actually appeared in print. For articles distributed exclusively on the newspaper's website, cite the electronic version in accordance with Bluebook Rule 18.2.2.
If you've performed a thorough check and you still can't verify the newspaper article citation, it may be time to contact the law review author who cited this document and request clarification from him/her.
