So I have a medium sized collection, mostly pathfinder and D&D (about 100 books total) that I used to keep on a 5-shelf bookcase from Walmart, which unsurprisingly bowed heavily under the weight. I recently moved into a new apartment, and with it I got a 3x3 cubby style case for all of my books. It looked great, supported the weight without bowing, until yesterday, when I heard a crack and now the right side is lopsided.

Does anyone have any other recommendations on shelves for their collections that can support a lot of weight and still looks nice? I don’t want to put a bunch of my books in storage, and I’ve seen some industrial bookshelves that would support the weight but aren’t very nice to look at.
