In the past, Irene Duranczyk would assign her students a $180 textbook and hope they had the money to pay for it.
Now, she still teaches the same introductory statistics class at the University of Minnesota. But the textbook is free.
Duranczyk is one of a small but growing number of college professors who are literally throwing out their old textbooks and replacing them with free alternatives on the Internet.
For most college students, the idea of free textbooks may sound like a utopian fantasy, especially when surveys show they can expect to pay $1,200 a year for books and supplies.
But in the past few years, dozens of "open textbooks" have been created, or adapted, online for a wide range of college courses — psychology, history, economics, foreign languages.
All are free to use, just "like a TED talk," said David Ernst, a national expert in open textbooks at the U's College of Education and Human Development.
Three years ago, Ernst created the Open Textbook Library at the University of Minnesota to serve as a national resource for the burgeoning roster of online texts. Now it has 184 titles on its virtual shelf.
Who would write a free textbook? "It's a question I get all the time," Ernst said. The answer: "They're not doing it for free." Instead, someone — typically, a foundation, government agency or nonprofit like OpenStax — pays the authors a flat fee. In exchange, they waive all royalties and allow their work to be shared freely.
