- MySQL by Paul DuBois, Third Edition
- This book is second only to the MySQL Reference Manual itself (some would say the reverse is true). It functions as both a reference guide and a tutorial; it is not particularly useful for a highly proficient audience.
- High Performance MySQL by Jeremy Zawodny
- Lessons learned in using MySQL at Yahoo. Official website: High Performance MySQL
- MySQL Certification Study Guide
- This book is of course a great resource for preparing to take the Core and Professional certification exams. It is also, however, a good source of general purpose information.
