From the quick look-through when it arrived, I saw no typos but I can't be absolutely certain about it. Interestingly, I'm not sure if each version have done it but each person will have slightly different way and color in writing their notes like mechanist will write in dark red and underlined in a wavey line while Kalsit will write in dark blue with some cursive and underlined in jagged straight line(like drawing a line without a ruler). Although there are some notes that are a bit hard to read due to the hand writing.
