(Original Review, 2010)
At university, after spending thousands on tuition, I then had to spend a lot, over 3 years, on books for my courses. More than half were written by the very professors that were teaching me. Quite frankly, it's a giant scam. Those professors have already been paid for the first material through their salaries. Why should we have to pay them again for copies of their pretty badly written books? Yes, these books are very expensive, and many don't deserve to be read. A few years ago, I was asked to review a chapter in a research text. The friend who sent me the invite told me over a drink that I was the third person asked, and would I please go easy on the papers. I said yes.
