An autograph or holograph is a manuscript or document written in its author's or composer's hand. The meaning of "autograph" as a document penned entirely by the author of its content (as opposed to a typeset document or one written by a copyist or scribe other than the author) overlaps with that of "holograph".
Autograph manuscripts are studied by scholars (such as historians and paleographers), and can become collectable objects. Holographic documents have, in some jurisdictions, a specific legal standing.
