I've gone through the Alaska NUFORC UFO reports (520 total) and the Alaska MUFON UFO reports (around 400) over the past few days, individually adding the better reports to a spreadsheet. In doing so, I've had ample opportunity to compare their collections.

NUFORC screens all reports before publishing them to their website. I've been in contact with the director, Peter Davenport, and they sound pretty swamped in their workload, but I've been impressed with their deliberation, and they don't hessitate to comment on a report if an explanation isn't confident but possible. They also keep out a lot of crud.

This is extremely obvious when looking through MUFONs collection. I excluded nearly 75% of the reports, keeping only 95 of the hundreds I waded through. They allow very obvious hoax reports, and obvious misidentifications. It is a poor collection, and I'm not sure if they have any vetting procedure before they publish the reports they receive. I did notice a lower than expected number of duplicate reports between the two, which is interesting to note.

I've gotta say though, I do appreciate NUFORC.
