Book nook

A book nook or a bookshelf insert^[1] is a miniature diorama designed to fit between books on a shelf.^[2] They often depict a form of a street or similar setting in a theme from famous books.^[2][3] Book nook can also make a form of a 3D model. They are similar to bookends but are placed in the middle of the books rather than on the ends.^[2]

Book nook created from a commercially available kit

The idea seems to have originated in 2018 from a Japanese artist called Monde.^[4][5] The concept became popular on Reddit, with the r/booknooks subreddit going from zero to 7,900 members in just two days.^[4][6]

The model is usually inspired by a theme from a famous book, e.g. Harry Potter (like popular Diagon Alley).^[2] People can buy book nooks fully assembled, or create them on their own.^[3] There are book nook kits that enthusiasts can use as a starting point.^[7]
