Website overview: Since 1996 the Study Guides and Strategies Website has been researched, authored, maintained and supported as an international, learner-centric, educational public service.
Permission is granted to freely copy, adapt, and distribute individual Study Guides in print format in non-commercial educational settings that benefit learners.
Please be aware that the Guides welcome, and are under, continuous review and revision.
For that reason, digitization and reproduction of all content on the Internet can only be with permission through a licensed agreement. Linking to the Guides is encouraged!
With the first few test images, you can calibrate your monitor by adjusting the brightness, contrast, clock/phase, sharpness, and gamma settings of the monitor. I recommend to go through them in the order they are presented. If you use this page in a shop, don't assume that the contrast and other settings are at reasonable values before making a judgement. The images are best viewed in a dim or dark environment and in full-screen mode. In most browsers, F11 switches to full-screen mode. If switching off the lights is not possible, try using a piece of cardboard to shield environmental light.
