Accessibility Statement

OSU Libraries and Oklahoma State University believe that education must be available to everyone; this means supporting the creation of free, open, and accessible educational resources. We are actively committed to increasing the accessibility and usability of the textbooks we produce.

This resource has been adapted by Kathy Essmiller from the BCCampus Pressbooks Guide by Lauri M. Aesophs. While Kathy Essmiller and OSU Libraries are thankful to learn from and adopt the outstanding accessibility features modeled by BC Campus publications, the process of customization and modification may have introduced some errors. Those errors are the responsibility of Kathy Essmiller, and do not reflect the work of Lauri Aesophs or the outstanding accessibility features designed by and included in BC Campus texts. Please use the form at the bottom of this page to share errors which surface. Thank you. ~Kathy
