  • The AMA Manual of Style does not have a specific example for referencing UpToDate.
  • For UpToDate citations the publisher recommends that you "cite the UpToDate topic as a chapter in a book titled UpToDate, edited by Ted. W. Post, published by UpToDate in Waltham, MA. There are no page numbers to cite, and the publication year for any topic should be the current year." [Wolters-Kluwer]
