Q. What's the difference between downloading a book as PDF or EPUB?

For many ebooks in our digital collections, you can choose your download format - PDF or EPUB. Books in PDF retain the look and feel of the print book (how it looked in print publication). EPUB allows you to resize the text of the book, which may be helpful on a tablet, phone, or other smaller device. It's like the typed out version of a book,versus an image of the page.
