A volunteer project currently underway aims to index the birth, marriage and death notices for the entire period of the Halifax Guardian’s existence. The index available so far represents progress to October 2011 and covers the years 1832 to 1864. This will be updated, at intervals.
The index is available in PDF format here
Central Reference Library, Halifax holds the Halifax Guardian on microfilm from December 1832, when the newspaper started, up to April 1921, after which it merged with the Halifax Courier, to become the Halifax Courier and Guardian.
