Your Library is private
Updated Nov 11, 2026
Everything in your Library is only for you: highlights, notes, bookmarks and summaries. Nobody else sees them, on the page or anywhere else.
When you want someone to see a highlight, share it. That makes a post, and the post is what other people see, either your followers or the people you pick. The highlight itself stays in your Library, private, whatever happens to the post.
Notes you had shared with your followers before this change became posts to your followers, with their replies.
