Answer 1

An e-book is a digital book that can only be found in digital form. It is a digital file that can be accessed on various electronic devices such as e-readers, smartphones, tablets, and computers. Unlike printed books, e-books don't have a physical form and can only be read on electronic devices. Therefore, an e-book is a source that would only be found in digital form.
