There are two different types of electronic textbooks sold in the VitalSource Bookstore: Reflowable Text VitalBooks and Page-Fidelity VitalBooks.

Reflowable Textbook (EPUB)
Reflowable textbooks do not maintain the layout of a traditional bound book. The text is responsive, so the font size can be easily adjusted no matter the size of the screen. These books conform to EPUB 3 industry standards.

Page-Fidelity Textbook (PDF)
The Page-Fidelity textbook maintains the look and feel of a bound book—the text is fixed and the screen size determines the size of the text.

Both types of eBooks support a wide range of features, including but not limited to: notes, highlights, text to speech, printing, syncing across devices, and more.

Information about the book's format is available on the Product Details page for that title in the vitalsource.com store. You may locate a title using our global search feature.
