Before the internet, before TV, before radio, newspapers ruled. There were literally hundreds of newspapers, published in towns and cities all over Australia, and they carried the daily life of Australians in all its petty detail. For historians, newspapers were a diamond mine; the information content was hugely valuable; the hard part was all the digging you had to do. It used to be that you would have to go to a library where a newspaper collection was held, and search manually through text on paper or microfiche. You had to be prepared to put in a lot of hard slog.
But then everything changed. A humanities researcher once told me that for Australian researchers, the National Library’s of Australia’s “Trove” newspaper archive marked a radical break: “There was a Before Trove, and an After Trove”.
