Pamphlet

A pamphlet is an unbound printed publication, without a hard cover or binding, that is typically shorter than a book. A pamphlet may take the form of a single sheet of paper printed on both sides and folded, sometimes called a leaflet, or it may consist of several pages folded and stapled or sewn together along one edge. Under a standardization definition used by UNESCO, a pamphlet is a non periodical printed publication of between five and forty eight pages, excluding its covers, distinguishing it from a book, which by the same definition runs to at least forty nine pages. Because pamphlets are cheap and quick to produce, they have served throughout history as one of the most important vehicles for spreading political argument, religious teaching and social commentary directly to a wide public, from Reformation era religious tracts to eighteenth century revolutionary pamphleteering to modern advocacy and campaign literature.
