How to Read Your GSU Ebook

Thank you for buying from the GSU Bookstore. Every sale keeps Global Sovereign University free. This page shows which file to use and how to open it on any phone, tablet or computer, with free apps and no extra cost.

Finding your book

Right after you buy, Gumroad, the company that runs our bookstore, sends you an email with a View content button. That button opens your book any time, so keep the email. You can also find every purchase in your Gumroad Library at gumroad.com/library.

Which file should I use?

Most GSU ebooks come with two files. You may download both.

EPUB

Best for phones and e-readers

The words rearrange to fit your screen, and you can make the text larger or switch to night mode. Some apps can read it aloud.

PDF

Best for tablets, computers and printing

Every page looks exactly like the printed book. Tap a QR code in the PDF to open its free lesson or tool.

Workbooks and our comic book come as a PDF only, because they are made to be printed and written in, or read as whole pages.
