The 5,000-word article was published on a militantly anti-abortion Web site, www.armyofgod.com.
It centers on how Rudolph gathered, stored and cooked his food, mostly boiled and fried corn, wheat and soybeans, while avoiding a massive law enforcement manhunt that at times got very close, CNN said Friday.
The manhunt began soon after a January 1998 bombing at a Birmingham abortion clinic and ended with his arrest in May 2003 when a deputy found him foraging through a garbage bin in Murphy, N.C.
In a deal to avoid the death penalty, he pleaded guilty in April to the Birmingham attack and three others in Atlanta, including the 1996 Olympics bombing.
The attacks killed two people and injured more than 110 people. He will be sentenced next month.
