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 netid and password can read these books on their computer, smartphone, or tablet anywhere and at any time. If you do not have a working netid and password, you can still enjoy access to these materials through one of the terminals at the Springfield College Library. 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.
