Dear Sandika
Personally, I find the quality is very high. How many manual corrections did you have to do?
Don't worry about the odd symbols you've highlighted. They are problems with the typesetting. Those were the days where the letters were pressed on lead blocks (like Lego), then "set" to make the page! (I was lucky to have visited the Lake House press as a school boy.)
Anyway, I will send the text back to its owner.
