Any book by Tim Rudman is worth study. This is no exception. The bible on toning techniques.

The book is beautifully illustrated and has many practical tips. Apart from various types of toning technique, Rudman also covers print finishing and useful printing controls. The appendix includes an f-stop table and a formulary.
