Editor's Note

Correction: The April 4 Notebook was based on a "Moving On" column by Jeffrey Zaslow that ran in The Wall Street Journal on March 15 with the headline, "Of the Places You'll Go, Is the Library Still One of Them?" Much of the material in the Notebook came from Mr. Zaslow, and we should have acknowledged that at the top of our piece. We offer our sincere apologies for the omission.
