There are markings and writing only in the index at the end of the book. Please refer to photos 7-11, which show all the relevant pages. As this is a used item, there may be some stains, wear, and folds (for Target 1400, there are some page folds like in photo 16). I couldn't find any page folds in 1900 during a quick check, but I apologize if I missed any. Please purchase only if you understand this.
