Vellum (derived from the Latin word vitulinum meaning made from calf, leading to Old French vÃ©lin, calfskin) often refers to a parchment made from calf skin, as opposed to that from other animals. It is prepared for writing or printing on, to produce single pages, scrolls, codices or books.
Vellum is a type of paper-like writing surface that has been used for centuries in various forms. Ancient vellum was made from the skin of mammals such as calves or goats. Modern forms are made from wood pulp cotton fibers that have been treated. It generally is more durable than paper and is most often used for special documents or other manuscripts that are meant to be preserved.
