Academic research is a staple of university libraries. Faculty depend on it for their own research, and students need it for their studies. But because of private publishing companies, who play a confusing and controlling role in the process of research creation, UNC Libraries is sounding alarms about the system's flaws. The publishing companies make money by selling research journal access to university libraries in confidential deals. UNC Libraries said there's an imbalance in the process, because tax payers subsidize research authoring, then subsequently have to pay again for research access. Rebels against the publishing giants advocate for open access — publishing online for free without paywalls — and say that continuing to buy into publishers' demands will impair scientific progress.
