Since 1996 the Study Guides and Strategies web site has been researched, authored, maintained and supported by Joe Landsberger as a 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. No request to link to the Web site is necessary. Please be aware that the Guides welcome, and are under, continuous review and revision. For that reason, reproduction of all content on the Internet can only be with permission through a licensed agreement.
