Here are some links to guidebooks and other reference material relating to Photoshop. The books on the list are ebooks available through the University of Illinois library. Students, faculty, and staff with a working PrideNet username and password can read these books on their computer, smartphone, or tablet anywhere and at any time. If you do not have a working PrideNet and password, you can still enjoy access to these materials through one of the computers at the Harold C. Smith Learning Commons. Also, while some of the resources and ebooks listed here are for Adobe Photoshop CS5 or earlier, they will still be very helpful for mastering CS6 Extended.
