Local Newspapers on the Web
There are several newspapers whose coverage included the Town of Warwick.
The two major weekly papers that covered news primarily of the Warwick Valley area (west of Mt. Peter) are The Warwick Advertiser (est. 1866) and the Warwick Valley Dispatch (est. 1885). Prior to 1866, local news was published in the newspapers of Goshen, NY, and Middletown, NY. Both the Advertiser and the Dispatch are preserved in microfilm form at the local history room of Albert Wisner Public Library, and these films are gradually being digitized.
The Greenwood Lake area was covered primarily by The Buzzer and the Greenwood Lake News, much of which have been digitized by the Greenwood Lake Public Library.
