Updated January 21, 2011 I have prepared a Google Maps listing intended to list every congregation in the world that practices exclusive psalmody. There are separate maps for each region. The maps will be published at: exclusivepsalmodychurches.wordpress.com and are also featured at Mark Koller's website: exclusivepsalmody.com I have been pleased to find more congregations than expected and work is ongoing. Information needs: any independent congregations that have been missed EP churches from non-EP denominations (easily overlooked) congregations anywhere that are considered "mission works" I have completed these EP denominations: American Presbyterian Church, Associated Presbyterian Churches, Australian Free Church, Evangelical Presbyterian Church of Australia, Free Church of Scotland (Continuing), Free Presbyterian Church of Scotland, Presbyterian Church of Eastern Australia, Presbyterian Reformed Church, Reformed Presbyterian Church of Australia, Reformed Presbyterian Church of Ireland, Reformed Presbyterian Church of North America, Reformed Presbyterian Church of Scotland, Southern Presbyterian Church, Westminster Presbyterian Church in the United States, as well as many independent EP churches. I have completed EP congregations in these non-EP denominations: Associate Reformed Presbyterian Church, Church of Scotland, Free Church of Scotland, Gereformeerde Kerke in Suid-Afrika, Orthodox Presbyterian Church, Presbyterian Church in America, RPC General Assembly, RPC Hanover Presbytery.
