It's summer, so if you are a college student textbooks are probably very far from your mind. But they shouldn't be. Next to tuition and room and board, textbooks represent the largest investment students make for college (yes, even more than "beverages").

Saturday's New York Times features an excellent profile on internet start-up Chegg. Chegg is an online resource where students can rent textbooks for a semester at a reduced rate, thus saving money on expensive books that either go into boxes or get sold back to the book store for ludicrously low rates at the end of the semester. As a resource, I would recommend you check out Chegg to see how you could benefit from the program.

But the Times piece goes further than describing Chegg's service. It turns out that Chegg is an excellent model for aspiring entrepreneurs. The site began in 2003 as a Craigslist for college campuses.

Yet the Craigslist model didn’t work. When classes ended in the spring, sellers couldn’t find many buyers online and sold their used books to the college store, often for pennies on the dollar. By the time students migrated back to campus in the fall, willing online sellers were few and far between.

So, in 2007, Mr. Rashid and Mr. Phumbhra went back to the drawing board and came up with the idea of renting books. At the time, Silicon Valley venture capitalists were focused on content, social networks and other businesses that could be supported by advertising, so finding investors wasn’t easy.

“People thought we were crazy,” Mr. Rashid said.

Now, as Chegg prepares for its third academic year in the textbook rental business, the business is growing rapidly. Jim Safka, a former chief executive of Match.com and Ask.com who was recently recruited to run Chegg, said the company’s revenue in 2008 was more than $10 million. This year, Chegg surpassed that in January alone, Mr. Safka said.

Chegg is a good example of recognizing your audience's wants and needs and adapting your business to successfully fulfill that niche. If you plan to start your own business after college, I recommend you read this article for an example of the persistence and adaptability necessary to run your own start up.
