THE EDITOR'S CORNER
Volume 50 : Number 2 : Page 0 : Feb 2016
Within the past year, JCO conducted an extensive online survey of both current and former subscribers, generating direct feedback on just what they like or dislike about our journal. Even on the basis of informal communications with our readers over the years, all of us on the editorial board had a strong sense that Pearls were among JCO's most popular features. Our more scientifically conducted online survey only confirmed that impression. As a result, we have decided to increase our emphasis on publishing Pearls - the eventual objective is to include one in each issue - while continuing to improve the quality and utility of these orthodontic gems.
