NOTE: I use a 0 to 5 system to rate what I've read. A book or article that has no rating at all is either waiting to be finished, or I've not had the chance to rate it yet.
0 = I disliked the book, and do not recommend it at all.
1 = The book was just tolerable enough to finish.
2 = The book was okay but nothing to write home about.
3 = The book was fair enough to read at least once.
4 = The book was enjoyable and definitely worth reading.
5 = I thoroughly enjoyed the book or it had a lasting impact.
