A facsimile (from Latin fac simile, "to make alike") is a copy or reproduction of an old book, manuscript, map, art print, or other item of historical value that is as true to the original source as possible.
Maps, for instance, were the focus of early explorations in making facsimiles, although these examples often lack the rigidity to the original source that is now expected.
[2] In the past, techniques and devices such as the philograph (tracing an original through a transparent plane), photostat, hectograph, or lithograph were used to create facsimiles.
Important illuminated manuscripts like Les Très Riches Heures du duc de Berry are not only on display to the public as facsimiles, but available in high quality to scholars.
[7] Facsimiles are best suited to printed or hand-written documents, and not to items such as three-dimensional objects or oil paintings with unique surface texture.
