This document contains URLs to several (but not all) free and legal CCSS text exemplars for grades 9-12, as listed in Appendix B: Text Exemplars and Sample Performance Tasks. These works are provided for educational purposes by the respective websites.
In some cases, works (or editions of works) are available online because they are no longer under copyright protection. In other cases, the site administrators have secured permission from the author or author's estate to provide access to the link for educational purposes. Additionally, I have included multiple URLs to a few works to provide additional options.
In turn, the text exemplars which remain absent from this list are still under copyright protection and cannot be shared in this manner. This affects several disciplines, but the History/Social Studies, Grades 9-10 Text Exemplars especially, as there are no free and legal links to these texts.
I hope this document is helpful.
