Books particularized by the importance and predominance of photography are often defined as photographic books or photobooks. They are phenomena characterized mainly by the way they relate photographic images to each other and to other sign systems (verbal text, painting, drawing, typography, graphic design, etc.), and by the way they explore the materiality of the book. In our thesis, montage is the principle by which photographic books are built and structured. It is the main process regulating the relations between the parties of these works. Four important Brazilian photographic books, published in the second half of the 20th century, are observed in this research. They are Viagem pelo Fantástico [Journey into the Fantastic], by Boris Kossoy (1971); Amazônia, by Claudia Andujar and George Love (1978); São Paulo Anotações [São Paulo Notes], by George Love (1982); and Silent Book, by Miguel Rio Branco (1997). We describe and analyze these works according to Eisenstein s theory. We verify that, as a principle, the montage can be observed structuring these photobooks in several levels. Each photographic image works as montage and, in turn, it participates in the juxtapositions on the pages, diptychs and triptychs. Sequenced, the parts defining the work act on each other obeying similar principles at new scales. This process occurs successively and produces the work as an image (in the sense proposed by Eisenstein).
