I’ve written about outliners a number of times here, and today I happened across another great resource. It’s another directory of available outlining software. This one is pretty extensive, has write-ups for most of the outliners it covers, and tries to cover all platforms, including PDA and web-based tools. It’s wiki based so in theory you can contribute to the resource, and it also has coverage of ‘antique’ outliners. Check it out of you’re a fan of this kind of tool.
