There's a phenomenon where the majority of books you read keep citing a specific earlier work, and you build it up in your mind to being something larger and more significant than it turns out to be. Of course, academic citations aren't necessarily a mark of significance; sometimes they're an acknowledgment of origins, of idea-lineages, of honoring those who first mapped out the territory. But it can still, sometimes, feel like a let-down when you finally get around to reading some highly-cited work and it doesn't live up to the image you've created in your head.
