About Epub and PDF e-books
NAS electronic books (or e-books) are mostly available in Epub format. Some of our books have instead been produced as PDFs, where this is better suited to the content. Please check the format information in the description for the book.
Epubs and PDFs can be read using computers, tablets, smart phones and some e-readers. If you would like to test whether your device can read these formats, you may like to try some of our free resources before making a purchase.
