[1] The word pamphlet for a small work (opuscule) issued by itself without covers came into Middle English c. 1387 as pamphilet or panflet, generalized from a twelfth-century amatory comic poem with a satiric flavor, Pamphilus, seu de Amore ('Pamphilus: or, Concerning Love'), written in Latin.
[5] Its modern connotations of a tract concerning a contemporary issue was a product of the heated arguments leading to the English Civil War; this sense appeared in 1642.
[3] In some European languages, this secondary connotation, of a disputatious tract, has come to the fore: compare libelle, from the Latin libellus, denoting a "little book".
Due to their ephemeral nature and to the wide array of political and religious perspectives given voice by the format's ease of production, pamphlets are prized by many book collectors.
There are numerous purposes for pamphlets, such as product descriptions or instructions, corporate information, events promotions or tourism guides and they are often used in the same way as leaflets or brochures.
