The words "Biblical concordance" typically invoke images of huge, densely packed reference books in a seminary library or a minister's study, and such tomes are still the mainstay of serious biblical scholarship. However, anyone who reads, studies, or is merely interested in the Bible can benefit from a good concordance, especially if it's in the form of easy-to-use software that's free to boot. Zahn Software, a Christian software developer and publisher, has a fine one with its Digital Bible Concordance 1.3 that not only contains an extensively cross-referenced guide to every word in the Old and New Testaments, each with scriptural verses referenced, but also includes two complete Bible translations and numerous extras, such as flash cards, daily devotionals, a talking Bible feature, and other aids to spiritual as well as scholarly contemplation of biblical texts.
Zahn's graphical interfaces are colorful and attractive dialog boxes containing simple controls with easy-to-read buttons and commands. The concordance is easy to use, as are the extras, by design, since the company's business is also its mission. It's handy for looking up the Bible's many unusual and archaic names and words, but you can also enter any word--say, "sloth"--and find appropriate quotes and verses that you can apply to everyday life.
Digital Bible Concordance is freeware. It downloads as a compressed file that requires Microsoft's .NET framework to unpack and install. It's certified to work in most versions of Windows up to Vista, but not yet in Windows 7, which testing confirmed.
