Editor's note: A headline in yesterday's City & Region section on a story about the return to Logan Airport of the body of an American soldier who died of wounds suffered in Iraq used quotation marks around the word hero. The headline should have made clear that quotation marks were being used because the pilot of the plane had announced to passengers that a hero was on board. Without that context, the headline appeared to call into question the soldier's heroism.
Correction: Because of a reporting error, yesterday's Personal Tech column about the new Apple iBook laptop computer in the Business & Innovation section incorrectly stated the amount of supplemental memory one could add to the iBook. It is 1 gigabyte of RAM, for a maximum amount of 1.5 gigabytes.
Correction: Because of a designer's error, performance artist Zhang Huan's name was omitted from an item about his appearance at the Museum of Fine Arts in yesterday's Sidekick section.
Correction: Because of an editing error, a story in Friday's City & Region section about Holli Strickland, a Westfield woman found fatally shot, incorrectly described another woman also found shot dead at the house. The woman, Constance Young, was Strickland's grandmother.
Correction: Because of a reporting error, a story in Saturday's City & Region section about a 23-year-old activist who was killed in a traffic accident misidentified the location of Hampshire College. The college is in Amherst.
