In the Dec. 9 "Dismal Science," Austan Goolsbee referred throughout to Health Savings Accounts. The Jan. 1 deadline he wrote about applies to Flexible Savings Accounts. Health Savings Accounts, another type of tax-preferred account for medical spending, do not have a time limit.

In a Dec. 8 "Music Box," David Yaffe originally and incorrectly identified the name of Homer Simpson's band as the B Sharps. It's the Be Sharps. It also had George Harrison's cameo quote wrong; he said "It's been done" not "It's been done before." Thanks to all the Simpsons fans for pointing this out.

In a Dec. 6 "Supreme Court Dispatch," Dahlia Lithwick attributed a one-line quip about "separate but equal" treatment for military recruiters at law schools to Antonin Scalia. The speaker was Chief Justice John Roberts.

In the Dec. 5 "Explainer," Daniel Engber incorrectly stated that pregnant women rarely get sonograms during the first trimester. The practice is not uncommon. The piece also implied that most women receive only one sonogram during their pregnancies. In many cases, a fetus will be imaged multiple times.

In a Dec. 3 "Today's Papers," Telis Demos incorrectly stated that the Washington Post was the only paper to report that military commanders admitted that government contractors were paying Iraqi media. In fact, the New York Times reported this, too.
