LDS historians Kate Holbrook and Steven C. Harper appear in a new (and short; about 5 mins) video giving an overview of the history of the Word of Wisdom (D&C 89):
The Word of Wisdom: Development and Practice
Harper is the author of a very good book on the Word of Wisdom:
The Word of Wisdom (Setting the Record Straight) (kindle ed. also available) (don't be put off by the fact it is part of the "Setting the Record Straight" series--it is one of the rare gems in that series [the others being Brian Hales' book on Mormon Fundamentalism and Jessie Embry's book on Mormon polygamy]).
Be sure to also check out Mike Ash's excellent refutation of the Tanners' chapter on the WOW in Mormonism: Shadow or Reality?:
Up In Smoke: A Response to the Tanners’ Criticism of the Word of Wisdom
