Why I finally organized my bookshelves by height instead of by subject

I resisted organizing books by height for years, treating it as aesthetically driven and intellectually lazy compared to organizing by subject or author. After finally trying it during a move, I noticed something I hadn't expected: I actually browse and rediscover more books this way, not fewer.

Subject-based organization means I only ever look at the section relevant to whatever I'm currently interested in. Height-based organization forces genuinely unrelated books to sit beside each other, and I've pulled several forgotten books off the shelf purely because a taller neighbor made it visually stand out, that I would never have rediscovered browsing a subject section I wasn't currently interested in.

It's not more efficient for finding a specific book you already know you want. It's turned out to be much better for rediscovering ones you'd forgotten you owned, which was never a use case I'd considered before actually trying it.
