"Readers always seem to think that the author has some control over the design of their books"

This quote by Donald Norman suggests that visitors often assume that writers have some impact over the style of their publications. This might be in regards to the physical layout of guide, such as the cover, font style, and also design, or the content of guide, such as the framework as well as story. Norman implies that visitors typically overstate the quantity of control authors have more than the style of their publications. In reality, writers might have some input right into the layout of their books, however most of the choices are made by the author. The author is in charge of the overall look of guide, as well as the writer might not have much say in the matter. This quote acts as a reminder that writers are not always in control of the style of their publications, which viewers should not assume that they are.
