* MySQL Cookbook by Paul DuBois
o A lot of examples of how to use MySQL. As with all of Paul\'s books, it\'s worth its weight in gold and even enjoyable reading for such a \'dry\' subject.
* High Performance MySQL, Second Edition, By Baron Schwartz, Peter Zaitsev, Vadim Tkachenko, Jeremy D. Zawodny, Arjen Lentz, Derek J. Balling, et al.
o \"High Performance MySQL is the definitive guide to building fast, reliable systems with MySQL. Written by noted experts with years of real-world experience building very large systems, this book covers every aspect of MySQL performance in detail, and focuses on robustness, security, and data integrity. Learn advanced techniques in depth so you can bring out MySQL\'s full power.\" (From the book description at O\'Reilly)

o The 'default' book to read if you wont to learn to use MySQL / MariaDB.
o This is the official guide to cover the passing of the two MySQL Certification examinations. It is valid till version 5.0 of the server, so while it misses all the features available in MySQL 5.1 and greater (including MariaDB 5.1 and greater), it provides a good basic understanding of MySQL for the end-user.
o This is the only book we know about that describes the internals of MariaDB / MySQL. A must have for anyone who wants to understand and develop on MariaDB!
