I don't think "seldom" is right here. I'm not sure how to define it. My attempt: "seldom" is like you're emphasising that you do something less than might be expected, or less than others. Examples: "My father's grave was a depressing place. I seldom went there." "I was expected to send a status update to my boss every day, but I seldom did so." "see on the books" sounds wrong. "see what books are there" / "see what's on the shelves" / "browse the books"

Each chapter haves an epigraph that for me it isI find to be so beautiful. Each chapter has an epigraph that I find to be so beautiful.
