I'm new to the site. I'm reading "The Stand," still have about 500 pages to go. BUT... in chapter 50, when Nick is in his new room, enjoying his new shelf with books etc., the scene starts with him and his "felt tipped pens." Later, he has a discussion with Ralph (about the meeting to elect a Representative Board). When Ralph leaves, Nick adds the third word "politics" to the encircled words "authority" and "organization", and he' ruminating "tapping his pencil against the circled words." HA! Surely someone's noticed this incontinuity before. That's all I wanted to say.
To answer your question, I personally have never noticed this "error." Those who may have noticed it, to my knowledge, have never spoken up about it. That said, many of us true-blue SK fans tend not to obsess about these types of things and just enjoy the read. I suggest you do the same!
