For nearly three decades The LaTeX Companion has been the essential resource for anyone using LaTeX to create high-quality documents. Just like the earlier editions, this completely updated third edition is designed to serve as the stable core resource for users: covering all aspects of document production, from detailed micro-typography questions and macro-typography (heading design, lists, mathematics, tables, graphics, fonts, page-layout, etc.) to bibliography and index production.
All chapters have been thoroughly revised and in many cases largely extended to describe new important functionality and features. More than 5,000 add-on packages have been analyzed in detail, out of which roughly 10% have been chosen for inclusion in The LaTeX Companion. All important aspects of these packages are described to provide the user once again with a satisfying one-stop-shop experience for the decade to come.
Following the concept of the earlier versions, the new edition is full of novel tips and tricks for using LaTeX in both traditional and modern typesetting, and also shows you how to customize layout features to your own needs--from phrases and paragraphs to headings, lists, and pages.
New to this edition:

• Inclusion of, or more details on, important new or changed large-scale packages, e.g., biblatex, fontspec, hyperref, mathtools, siunitx, tcolorbox, tikz, and unicode-math, to name just a few.
• Coverage of newer engine developments, e.g., the use of Unicode engines with LaTeX.
• Discussion of all vital changes to LaTeX itself, which is is undergoing a transformation to keep it relevant in the years to come. Examples are the new hook management system for LaTeX, the extended document command syntax, and the inclusion of the LaTeX3 programming layer into the LaTeX format.
• Inclusion of many new, useful (smaller) packages in all chapters--each offering additional functionality.
• Two new chapters devoted to the use of high-quality fonts for text and math (OpenType, TrueType, and Type 1), now available for use with LaTeX. They offer a comprehensive set of samples to choose from (more than 120 text font families and 40 math font layouts), compiled with the help of an expert font designer.
• Revised discussions of multi-lingual support by the authors of the babel system to typeset text from a wide range of languages and cultures.
• The chapter on bibliography generation now also covers the styles made available with biblatex and biber.
• More than 1,500 fully tested examples (an increase of 30%) that illustrate the text and solve typographical and technical problems--all ready to run!

Part I contains chapters on: Introduction to LaTeX and its history LaTeX's document structure Basic formatting tools (paragraph level) Basic formatting tools (larger structures) Page layout Tabular material Float handling Graphics generation and manipulation Font selection and encodings
