The 'LaTeX Book' is for the professional or student who needs to quickly learn how to write and typeset using LaTeX or wants to advance their LaTeX knowledge in order to write articles, books or presentations containing mathematical formulas. As a spin-off of Grätzer’s well-received Math into LaTeX, this book retains the simple, example-based, visual approach, with sample articles to demonstrate the basic structure of LaTeX and AMS articles. This book includes a new chapter on implementing LaTeX on multiple platforms and an entirely new section on creating presentations; he discusses both the simpler FoilTex package and the more sophisticated Beamer package. Rounding out this book is a major revision to the amsart document class. This comprehensive and up-to-date guide is the result of over two centuries of LaTeX experience. As Grätzer began as a user of LaTeX, he writes from a user’s perspective, making this guide accessible to the beginner and rewarding to the more experienced LaTeX user.
