Because the Index was originally created by the Sydney Dead Persons Society, its strength lies in notices from NSW papers - including in excess of one million notices from the Sydney Morning Herald alone. However, the representation from papers from other states continues to grow, with additional papers being regularly added, so that the Index can now truly be considered an Australian index.

Indexing is being continuously carried out by a team of volunteers, too numerous to mention individually, who give freely of their time to ensure the site continues to grow. Site updates occur every couple of weeks, and more often in periods of high activity.

The index itself cannot by definition be considered a primary source of data, but is purely a research aid to direct the researcher to the original source of a notice.

As well as the main index, there is a supplementary index containing historical data which does not fit into the main index. This comprises RSVP notices from the Sydney Morning Herald for the period 13 Oct 1998 to 19 Jun 2005.
