Hi there! How to cite a book from a website in AMA style?

Hi Zoe,

AMA Ebook citation is pretty similar to a general printed book reference. As it is digital information, URL should be given and Accessed Date mentioned at the end of reference. When referring to a book you found online, stick to the following formula:

Author(s) Name (Last Name First Initial Middle Initial), ed.
Book's Title: Book's Subtitle,
Edition Number (indicate the last edition),
Publication Place: Publisher, Year,
Accessed Date (Month-Day-Year).
