A story that ran on the front page of Wednesday’s edition about the flow of guns from Maine to Massachusetts contained an error. Federal law requires that a criminal background check be run on anyone seeking to buy a handgun from a federally licensed dealer, including those sold at gun shows. Unlicensed dealers selling at gun shows are not required to do a background check. Most checks, through the FBI’s National Instant Criminal Background Check System, take about 15 minutes, according to local dealers.

A story published in Wednesday’s State section about the town of Corinth’s new welcome signs listed the wrong sign that has yet to be installed. The sign at the Hudson-Corinth town line on Route 43 hasn’t been put up.
