When Ordering A Demographic Profile...
www.mapquest.com is a resource we commonly use to identify details for unusual study area requests. If you are requesting a study based on a street intersection, you may want to check it here to make sure we both "get on the same page."
www.juggling.org/bin/un.cgi/map-find is helpful for situations where no address exists, like a new or potential church property site. Nine map layers allow you to determine the latitude & longitude for any location you can point to through successive magnifications.
Evangelism...
http://www.ethnicharvest.org/bibles/ is a wonderful source if you are witnessing to someone who needs to read scripture in their native language. Many links are to online Bibles as well as sources for purchase. Listings are by language as well as by country.
