A book's format, or physical make-up, reflects the ideas of both its author and its publisher. A book reviewer might mention characteristics of format, in relation to suitability and aesthetics. Is the book's size convenient? Is the binding durable? Is the print type legible? Do illustrations, diagrams, and maps, if any, aid the reader's understanding of the material? Is the index correct and complete? Are bibliographies and reference lists present?
In response to artwork present in Ken Lamberton's Wilderness and Razor Wire, John Calderazzo comments on both the exactness of the drawings and the possible meaning of this detail-orientedness to Lamberton's life: "[J]ournal entries and small essays [are] complemented by drawings of tarantulas, conenose beetles, horned lizards, and other desert creatures in almost photo-realistic close-up. This is why I suggested that Lamberton may not find himself any closer to 'nature' when he's finally free. How can he get more intimate? . . . All of his drawings, in fact, are rendered in extreme close-up, like visual infatuations writ large. Nothing seems to exist in the distance, which makes me wonder if anything ever does for Lamberton, or ever will."
