WSJ.com - Personal Technology: GuruNet as a Reference Tool Goes Beyond Search Engines "But I have been testing a new, expanded version of a clever piece of Windows reference software that can give you quick answers instead of links. Those answers are presented in a format designed for reference work and are drawn from known, standard sources. Oh, and this program will also throw in that same general Google search, plus results from other search engines, in case its answers leave you wanting more.
The software is called GuruNet and can be downloaded from www.gurunet.com. The product of a small Israeli company called Atomica, GuruNet has been around for years as a free utility, but now it has been greatly expanded and reorganized, and is being sold for $34.99. You can try it free of charge for two weeks before you're asked to pay. If you decide not to pay, you can still use it as just a dictionary and thesaurus."
I've been using Atomica/GuruNet (fascinating they should revert to their original product name) for several years; it's a fantastic tool.
