About Erratic Impact's Bookshop

We are proud to be an associate member with many bookstores, including three key merchants: amazon.com, Powell's Books and Booksense.com.  This means that you can securely order both new and used books over the Internet directly off the pages of the PRB.  If you do, the PRB receives a small referral fee (at no extra cost to you) which helps us build and maintain an even better website for your research enjoyment. 

Throughout Erratic Impact's website, we have made every effort to make your book finding easy and your purchasing convenient.  To access the best inventories, and to keep things as simple and ordered as possible, our emphasis on searching and linking is with Amazon and Powell's, although we encourage you to explore the other eleven booksellers we've partnered with.  

Again, thank you for shopping at Erratic Impact.
