A.J. Jacobs

He spent a year reading the entire Encyclopaedia Britannica and writing The Know-It-All, an account of what he learned.

Now author A.J. Jacobs has accomplished another annually retentive feat: Living life the way the Good Book says we should.

The Year of Living Biblically: One Man's Humble Quest to Follow the Bible as Literally as Possible chronicles Jacobs' attempts to follow every rule in the Bible — and considers the lessons he learned along the way.
