I am sure that I will find things about this tool that I don't like, but so far, it looks like a great way to help me organize my collections of interviews, images, recordings, observations, links, etc. according to project and to record links and themes within them.
NVivo seems to have sprung directly from version 2 to version 7 (how or why, I don't know!). They offer other qualitative research software, so that may have messed with the numbering scheme.
At any rate, check out the newest version. You can download and try it for frree for 30 days - just the right amount of time between grading papers and resuming the lecture routine.... Go to QSR to download NVivo 7.
