Yes, built-in bookshelves are outdated. Not only do they take up valuable floor space, but they can also be difficult and expensive to repair or replace if they become damaged. Instead, consider using open shelving or cabinets to store your books. This will not only save you space, but it will also make your books more easily accessible and allow you to show off your collection to visitors.

No, built in bookshelves are not outdated. They are a great way to save space and they can be very aesthetically pleasing. However, they may not be the best option for everyone. If you have a small home or if you are short on space, then built in bookshelves may not be the best option for you. In that case, I would recommend using floating shelves or wall shelves.
