Grossmont College is looking to expand a program that offers free textbooks to students. The Open Educational Resources program, or OER, allows students to download digital versions of textbooks for free. College officials say it can save students more than $1,000 each semester. In the 2018-19 school year, Grossmont students have already saved nearly $1.3 million. "We realized students were making decisions like, 'Do I want to buy food today or do I want to purchase my textbook?'" says Professor Dave Dillon, who has championed the program at Grossmont.
