Lena Marvin, a reference and the institutional repository librarian for University Libraries at the University of Missouri–St. Louis, knew exactly what to do when a student came to her with a unique dilemma. He had learned calculus in his first language, Spanish, but he needed to learn it in English to keep up with his math classes. “I was like, ‘Oh, well, here’s an entire calculus book. You can have the whole thing online. It has interactive elements. It’s all there,’” Marvin said. “That made me feel happy.” What Marvin provided is what’s known as an open educational resource.
