First published by World Vision in 1985, this is now assembled and published by Genesis Publications and Media. It has over 4,000 major Christian ministries that cover a very wide range of subjects in many categories. Although some are not specifically focused on needs in the developing world, many others do. You can find information on medical supplies, agriculture, clean water, and various other topics similar to what is on this HelpingWorldwide.org website.
Christian Ministry Sourcebook is updated and published every year. You can get a free download of it via their website.
