Back-to-school shopping has started, and for college students, that means figuring out how to pay for at least one big expense: textbooks.
The average student at a four-year public college spends about $1,200 per year on course books and materials, according to the College Board, a nonprofit organization whose members are made up of colleges and educational institutions.
The bill has climbed dramatically in recent years.
From 2002 to 2012, textbook prices rose at an average rate of 6 percent annually, or about three times the rate of inflation, according to the Government Accountability Office.
Critics say the frequent rollout of updated editions for textbooks, often with little new content, has helped drive up prices. Workbooks and other materials that get bundled with books can also inflate costs.
Still, some progress has been made recently toward helping students afford their textbooks.
Because of the 2008 Higher Education Opportunity Act, publishers are now required to inform college faculty about substantial changes to a book's content, along with pricing.
And schools are required to list a textbook's price and International Standard Book Number in course registration materials.
The idea is that with more information, faculty and students should be able to make cost-saving choices. There are also a number of ways for students to get textbooks, from buying used to renting for a semester.
Shop online. A book's ISBN is a unique identifying numeric code. Punch it into a search engine -- whether at your college bookstore or an online marketplace -- and you can easily compare prices.
It's worth shopping around.
Students taking Intro to Biology this fall at the University of Oklahoma, for example, will need the textbook, "Campbell Biology." A new copy of the latest edition runs $241 at the college bookstore.
Rent. Buying a hardcover copy is not the only way to get a textbook these days.
You can also rent, either from online retailers or college bookstores. In fact, almost all of the 3,000 members of the National Association of College Stores now have a book rental program.
Many rental agreements last a full semester, including final exam periods. And when the term is up, you simply return the book. You don't have to worry about storing or reselling the book.
Go electronic. Finally, if you don't mind reading your assignments online, consider an e-textbook.
Digital books can be rented or bought, again for a fraction of the cost of buying new. You can access the text on most devices (you don't need a dedicated e-reader). And there are tools that let you highlight, take notes and so on.
