Come for the price, stay for the quality

A project like this doesn't happen without some expenses. And if you like this model of textbook publishing, then helping with expenses and rewarding the author with royalties will help show others that this model is a viable alternative. Much of the cost of creating this textbook has been borne by my employer, the University of Puget Sound, such as website hosting, office supplies and time to pursue this professional activity. However, there are out-of-pocket expenses, such as sending out review copies or purchasing ISBN numbers.
With a traditional textbook, an author might expect to receive an amount around $5 for each copy sold. So this is a suggested amount, but you are of course free to determine exactly what you think is appropriate. If you purchase a physical copy, then a $5 royalty is included in the price.
Payments
Dwolla is a payment service like Paypal, but their model is a flat $0.25 fee per transaction, so you can be sure that whatever you donate, almost all of it will go to the project. The link below will take you to a page you can use to initiate a transaction sent to me. Thanks for your support!

A check (in US funds drawn on a US bank, please), is another way to go. US or Canadian cash would be a final resort. My postal address is:
