Other forms: booklets
A booklet is a thin book with a paper cover. A few dozen pages, stapled or stitched.
The -let ending means small, the same one that makes a piglet and a droplet. It sits between a leaflet, which is a single folded sheet, and a book proper. Instructions, exhibition guides and information from a council all arrive as booklets. The word promises modesty, which is why nobody publishes a novel as a booklet, and a pamphlet is the same object with an argument in it.
