We're excited to introduce the redesigned repository.ou.edu website, launched in October 2023! This redesign is part of a larger improvement plan, with additional changes coming next year.

We invite you take a moment to share your thoughts about the website through a brief 5 minute survey: repository.ou.edu feedback survey.

Your feedback is vital and will help shape the future of repository.ou.edu.
