In the Dec. 22 "Moneybox," Daniel Gross misspelled Wall Street Journal reporter Laura Meckler's name. He also undercounted the number of registered traveler program pilot projects. Originally he wrote that there were four. There were five.

In the Dec. 20 "In Other Magazines," Melonyce McAfee incorrectly spelled the surname of Arthur MacArthur as McArthur.

In the Dec. 20 "Technology" column, Adam L. Penenberg originally and incorrectly stated that Intel's microchips are "less than 100 nanometers in size" and are so small that factory workers can't see what they're manufacturing. It is the transistors on the chips, not the chips themselves, that aren't visible and are less than 100 nanometers in size. Penenberg also stated incorrectly that a nanometer is "the equivalent of about 100 atoms." A nanometer is roughly equivalent to a line of 10 hydrogen atoms.

In a Dec. 19 "Books" article, Stephen Metcalf incorrectly wrote that that Vladimir Nabokov gave the character Dolores Haze, aka Lolita, an IQ of 150. Lolita's IQ was 121. The sentence in question has been removed. The article also may have given the impression that Lolita was 14 years old at the beginning, or for the duration, of the book. In fact, she is 12 at the beginning and 14 when Humbert Humbert settles them in Beardsley.

In the Dec. 19 "Press Box," Jack Shafer mistakenly stated Justin Berry's current age as 18. He is now 19.
