A pamphlet is an unbound booklet (that is, without a hard cover or binding). It may consist of a single sheet of paper that is printed on both sides and folded in half, in thirds, or in fourths (called a leaflet), or it may consist of a few pages that are folded in half and saddle stapled at the crease to make a simple book. In order to count as a pamphlet, UNESCO requires a publication (other than a periodical) to have "at least 5 but not more than 48 pages exclusive of the cover pages"; a longer item is a book

• Pamphlets are useful in business communications.
