After assessing all the information that needed to be presented, I chose the structure of an eleven-column grid system. This allowed the main text to be the focal point, provided plenty of space around it, enabled the use of pull-out quote boxes, and made the five-level deep heading hierarchy typographically simpler. This grid is defied by the tables which are centred on the page to create more visual interest, and the in-line diagrams which are allowed to spill out into the negative space. The main body text is Caslon Pro. Both Julius Sans One and Europa are used for the five-level headings hierarchy. Europa is also used for text clarity in the body of tables, and in the running headers. In the tables three weights of Europa are used to structure information. In an unusual move for me, a fourth font is also used (though only three times in the entire book) to create visually-different section dividers to break the book into thirds.
