I am well aware of the ongoing ebooks vs. physical books debate, and I have no interest in kindling that fire here.
Instead, I am seeking recommendations for books that are arguably better in physical form due to their makeup. House of Leaves is a perfect example, with its textual trickery essentially requiring physical pages. Coffee table books also fit the bill, for example. Some textbooks and reference books technically do as well, though I'm not interested in recommendations in those areas unless you have something in mind that's an absolute standout.
