Lovers of paper books: they want to open a new – and only their own – book, inhaling the smell of printing ink, because a book is a special value, an almost magical artifact; want to read the book at their own pace, without any library deadlines and re-read if they feel sad; are afraid of other people’s germs on library books; appreciate the rich library that fosters good taste in children and grandchildren.
