What is an eBook?
An eBook is a book designed for electronic reading using a computer screen or portable device, such as an iPad.
What if I lose my PDF file?
When you download your eBook, be sure to make a backup copy. It is the nature of computers to crash on occasion. A proper backup strategy can save you a lot of grief. For that reason, we also recommend that you keep at least one copy on your desktop/laptop computer and not only on your tablet or other mobile device.
May I share the PDF file with others?
Your purchase entitles you to use the book on any device owned by you. Providing the PDF file to others is a violation of copyright and of the terms of sale. Our eBooks are priced to be affordable and we believe that most people can be trusted to do the right thing. For that reason, the files are not protected from piracy. Please respect the work that went into them and advise anyone interested to purchase their own copy. This will ensure that authors like Guy can continue to offer their work in an accessible and affordable format, and be fairly compensated for their work.
Are eBooks also available in print?
No. eBooks are designed for digital reading.
Can I print my eBooks using my own printer?
No. eBooks are meant to be read and used in digital form. Most PDF readers allow for highlighting, bookmarking and other functions aimed at making them as flexible as paper publications.
May I use your eBooks as teaching material for a class?
Yes, however you will need to purchase individual copies for each student. If you wish to inquire about bulk pricing, please contact us.
May I re-sell your eBooks?
You may join our affiliate program and earn a commission on every item you sell. You may not sell the PDF file directly without prior written approval from the author.
I'm having trouble downloading the file(s).
While most users should have no problem downloading the PDF files, they are fairly large and may present challenges for those with slow Internet connections. By default you are granted 5 attempts to download each file. If you exhausted all 5, we recommend that you purchase the CD Delivery option to have the files sent to you on a disc. You only need to add CD Delivery to your cart once. Multiple eBooks can be placed on a single CD.
If you already purchased the eBooks, you may place a separate order just for CD Delivery and send an email to email@example.com asking for your purchases to be mailed to you on a disc.
