Books, with or without text in which the essential information is conveyed through a collection of photographic images. These may be authored by one or more artists or photographers, or arranged by an editor. Generally the images in a photobook are meant to be viewed in context, as parts of a larger whole. Most often used to refer to mechanically reproduced and commercially distributed works. For albums made up of mounted photographic prints, with or without identifying information, use "photograph albums."
