I found a headline on ActiveWin.com linking to the Office Research Service SDK on MSDN. It sounded intriguing and so I checked out the documentation. I couldn't find the actual SDK and so I hunted around in the node and finally came up with the right one. You can download that SDK, along with the SDK's and tools listed below from Microsoft Office Downloads. XML Toolbox for Microsoft Office Word 2003 Office 2003 Smart Document Software Development Kit (SDK) Office 2003 Research Service Software Development Kit (SDK) Microsoft Office 2003 Web Services Toolkit I was looking at the samples and this stuff seems very cool. I imagine that a service that exposed RSS feeds while working in Word would be quite useful for some of us. There's even a Google sample.
