In a very limited number of instances, it may be required to remove an article from the online database. This will only occur if the article is clearly defamatory or violates the legal rights of others, if it is, or we have good reason to believe it will be, the subject of a court order, or if it poses a major health risk if acted upon. The metadata (Title and Authors) will be preserved, but the text will be replaced with a message indicating the article has been removed for legal reasons
