Students and faculty at Rutgers Camden campus gathered to address the issue on Tuesday.
Advocates point to a recent national report that found that many students have been automatically billed for an entire semester's worth of online textbooks without their knowledge.
Representatives from Rutgers University say they do not put charges for full textbooks on bills.
In certain courses, Rutgers instructors use digital course materials that are often delivered through a bulk licensing model that many times comes at a reduced cost.
Rutgers also maintains the Open and Affordable Textbooks Program, or OAT, which is designed to make higher education more affordable.
The OAT Program is an incentive initiative that awards funds to faculty for replacing expensive textbooks with free or low-cost materials to reduce student costs.
Through OAT, it has saved Rutgers students over $13 million since 2016.
