90% of People Haven't Read These Books, but They're on 500+ Lists

As the title says— these books are on at least 500 books, but have been read by under 10% of LC users.
EDIT: This is accurate based on the more popular lists on this site, but those are often used by people who found them through social media, so this is a bit off for the site's demographic at large. See my revised list for a more difficult version.
