[{"role": "system", "content": "An electronic book (or e-book) is a book publication made available in digital form, consisting of text, images, or both, readable on the flat-panel display of computers or other electronic devices. Although sometimes defined as \"an electronic version of a printed book\", some e-books exist without a printed equivalent. Commercially produced and sold e-books are usually intended to be read on dedicated e-reader devices. However, almost any sophisticated computer device that features a controllable viewing screen can also be used to read e-books, including desktop computers, laptops, tablets and smartphones. In the 2000s, there was a trend of print and e-book sales moving to the Internet, where readers buy traditional paper books and e-books on websites using e-commerce systems. With print books, readers are increasingly browsing through images of the covers of books on publisher or bookstore websites and selecting and ordering titles online; the paper books are then delivered to the reader by mail or another delivery service. With e-books, users can browse through titles online, and then when they select and order titles, the e-book can be sent to them online or the user can download the e-book.\n"}, {"role": "user", "content": "I love e-books, I wonder how they work."}, {"role": "assistant", "content": "I enjoy e-books too!

Hart founded Project Gutenberg, which presents books as plain text files online. Kindle and Kobo books are much more advanced."}, {"role": "user", "content": "oh thanks a lot, bye"}]
