From "Holbrook's Pocket Guide 1872":

The Newark Evening Courier, office 832 Broad Street, Frank W. Potter, Editor and Proprietor, is a Daily and Weekly paper, the daily being published in the afternoon.  The Courier was established June 18th, 1866, and is an excellent and enterprising paper.  It is Republican in politics but was favorably received by all parties from the first, and occupies a place in the front rank of State journalism. It gives careful and constant attention to the best interest of the city.  During the past twelve months it has presented, and still continues to present, weekly to its readers a well written and interesting account of some branch of our manufactures.  In its reports of municipal and legislative proceedings, public meetings and improvements, police items and passing events, the Courier is full and correct, and consequently its pages are always fresh and readable.  It is also rewarded by a good advertising patronage and increasing circulation.
