Harry Plantinga

Harry Plantinga is a professor of computer science at Calvin College, and founder and director of both Christian Classics Ethereal Library and www.hymnary.org, a comprehensive planning tool for choosing music for worship.

He also collaborates on preachingandworship.org, a website that aims to provide easy access to excellent on-line resources for preparing sermons and worship services for a wide range of denominations and traditions—much like a Google, Bing, or Yahoo search, specifically designed for preachers and worship planners.
