Once upon a time, only typesetters needed to know about kerning, leading, ligatures, and hanging punctuation. Today, however, most of us work on computers, with access to hundreds of fonts, and we’d all like our letters, reports and other documents to look as good – and as readable – as possible. But what does all the confusing terminology about ink traps, letter spacing, and visual centring mean, and what are the rules for good typography? Type Matters! is a book of tips for everyday use, for all users of typography, from students and professionals to anyone who does any layout design on a computer. The book is arranged into three chapters: an introduction to the basics of typography; headline and display type; and setting text. Within each chapter there are sections devoted to particular principles or problems, such as selecting the right typeface, leading, and the treatment of numbers. Examples throughout show precisely what makes good typography – and, crucially, what doesn’t. Authoritatively written and designed by a practitioner and teacher of typography, Type Matters! has a beautifully clear layout that reinforces the principles discussed throughout.
Legibility literally means "able to be read". This ability to be read combines visibility (the quality of being seen) with comprehension (understanding). Perception has a lot to do with legibility. It is by this complex process that we select, interpret and organize sensory stimuli into coherent pictures; then these shade into perception as we relate what we see and feel with past learning.

Presenting some recent results on the construction and the moments of Lévy-type processes, the focus of this volume is on a new existence theorem, which is proved using a parametrix construction. Applications range from heat kernel estimates for a class of Lévy-type processes to existence and uniqueness theorems for Lévy-driven stochastic differential equations with Hölder continuous coefficients. Moreover, necessary and sufficient conditions for the existence of moments of Lévy-type processes are studied and some estimates on moments are derived. Lévy-type processes behave locally like Lévy processes but, in contrast to Lévy processes, they are not homogeneous in space. Typical examples are processes with varying index of stability and solutions of Lévy-driven stochastic differential equations. This is the sixth volume in a subseries of the Lecture Notes in Mathematics called Lévy Matters. Each volume describes a number of important topics in the theory or applications of Lévy processes and pays tribute to the state of the art of this rapidly evolving subject, with special emphasis on the non-Brownian world.
