Apologies if I'm restating common knowledge, but did everyone know that the 1838 Ordnance Survey Map of Mayo (1. Edition, Six-Inch) is available for viewing online at the Mayo County Library web site? http://www.mayolibrary.ie/maps/data/MapsData/index.htm Is that the same or different from the Discovery maps mentioned in this recent thread?

Joe~ Different in the sense that these are versions updated in 1999. I had the same question to the website. The base maps were from 1975 and updated in 1999.

Hi Joe, The 1838 Ordnance Survey maps on the County Mayo library website are from 1838 when the British Government first attempted Ireland-wide mapping. They did it because they wanted to implement land valuations for taxation purposes and they used the resulting maps for the Poor Law taxes when they passed the Poor Laws in 1838. Since they did the mapping for taxation purposes in 1838 and the country had never been mapped before, needless to say they didn't get alot of cooperation locally to help them develop the maps. Those maps, therefore, are very primitive and not complete. The Discovery maps referenced are numbered maps that cover the entire county of Mayo (they're done for all counties in Ireland) and the latest versions are from ca 1999. There are 9 or 10 Discovery maps that are like puzzle pieces and when put together cover all of County Mayo. See: http://www.osi.ie/mapping/maps/discovery.asp The maps on the bernieworld.net website are only for the Westport area in western Mayo but Bernie has used the Ireland Ordnance Survey Discovery maps (#30 and 31 according to Pete Schermerhorn) which he's posted online. Compared to the 1838 maps, the Discovery maps are much better and of course more detailed.
