In the Aug. 7 installment of "The End of America," Josh Levin originally stated that Mormons are counseled to keep a two-year supply of food. In 2007, the church advised families to keep a three-month supply plus stores of food for longer-term needs.

In an Aug. 5 "Prescriptions," Timothy Noah called the notion that Medicare was not a government program "errant nonsense." This was an incorrect usage. The correct phrase is "arrant nonsense."

In the Aug. 3 "Fighting Words," Christopher Hitchens originally and incorrectly claimed that Sen. Daniel Inouye lost an arm fighting in the Pacific. He lost the limb while fighting in Italy.

In the Aug. 3 " Prescriptions," Christopher Beam incorrectly stated that Families USA was running ads against health care reform. The group is in favor of reform.

In the July 29 "Medical Examiner," Kate Klonick incorrectly stated that an IUD has to be placed by a gynecologist. It can be placed by a trained gynecologist, midwife, or nurse practitioner.

In the July 24 "Medical Examiner," Christopher Lane included two sentences about an article from the St. Petersburg Times on prescribing psychiatric drugs to very young children. The St. Petersburg Times article was about the sharp decline in such prescriptions in Florida in 2008, following new regulations, but the Slate piece reported only the much higher rates of prescriptions in 2007, misrepresenting the contents of the St. Petersburg Times' reporting. Those two sentences have been deleted.

In the June 29 " Books" column, Johann Hari originally included two phrases that could have given the incorrect impression that Richard Bernstein has attended, or approves of, brothels where women are coerced. This was not Hari's intention or Slate's. We have amended these sentences to clarify that Bernstein does not approve of forced prostitution.
