Our Textbook was featured in an NGLC Grant titled "Ohio's Scaffold to the Stars." Part of this project involved mining the internet for additional free resources to help students with material in our textbook. While the final vision was never realized (grant money always runs out!) many students have found the following materials helpful. Links to libraries of resources are embedded in the homework exercise sections. (Note: some users have experienced bugs with Internet Explorer, so using another browser (Chrome, Firefox, Safari) is recommended.)
