Chegg has established itself as a student resource, intended to be a place where all students could go to find textbooks and to get help getting through the courses for those books. Through Chegg, you can rent, buy, and even sell back textbooks. According to Chegg, about five million students use their services every year.
The company was created in 2005 and is based out of Santa Clara, California. Primarily, they handle all things textbook, but they have the occasional other type of book in their library as well, so as a potential customer, you can search through their inventory to see if they carry the book you need.
