An autograph (from the Greek: αὐτός, autós, "self" and γράφω, gráphō, "write") is a document transcribed entirely in the handwriting of its author, as opposed to a typeset document or one written by an amanuensis or a copyist; the meaning overlaps with that of the word holograph.
Autograph also refers to a person's artistic signature. This term is used in particular for the practice of collecting autographs of celebrities. The hobby of collecting autographs is known as philography.
