<human>: What's the difference between an e-book and a regular book?
<bot>: The main difference between an e-book and a regular book is that an e-book is digital, while a regular book is printed on paper. An e-book can be read on various devices such as computers, tablets, and smartphones, while a regular book requires a physical copy to be read. Additionally, an e-book can be stored in digital libraries, allowing for easy access from any device, while a regular book must be kept in its original form.
