There’s tons and tons of commercially available book displays out there, but that doesn’t always mean you can find QUITE what you wanted. Or at the price you wanted. Instructables is a website full of do it yourself projects, illustrated with photos. Some of them are brilliant, easy projects… some you look at them and are pretty sure this person is way handier than you and if you tried it you’d be looking at a trip to the emergency room. Bookshelves are a favorite project and there’s some fascinating takes on them. Click the link to see the instructions on how to make them!
