As important as the design of a book's cover and binding is for readers, authors, publishers, and booksellers, the interior typography is at least equally important as a mediator of structure and aids in orientation. It can be serious or playful, it can reference historical elements or be distinctly contemporary – or both. Through a clear design of the entire book, including the choice of papers and binding materials, it can express trust in the seriousness and love of those involved with the book. Friedrich Forssman, one of the most prominent German book designers, shares his approach to book design: from the general to the specific, from the inside to the outside, from typographic details to production.
