Once you know which title you want, click on it to go to its detail page. You should now see a page with a much larger picture of the cover and a description of the title.
If you want to add this title to the virtual shopping cart, click on the "Buy" button. All of our titles have a download option. Some titles are also offered as a print version or as a combination of print and download. If print versions are available, you can select this option if you prefer a printed book.
When you click "Buy", the selected format will be added to the shopping cart. After clicking the "Buy" button, you will be taken to a page with the contents of the shopping cart. You now have the choice of either going to the checkout or showing other titles.
