Links to documents on the page above, overview copied below:
This is quite possibly the largest collection of publicly accessible UFO
documents in the world, drawing from as many sources and countries as
possible. (Special thanks to The Black Vault, the excellent collections of
which helped identify what countries and agencies have released files.) If
you know of any other files that should be included, please contact me.
This page includes the 10,000 Project Blue Book reports which were censored
by a copyright claim from Ancestry.com subsidiary Fold3 after they were
posted on The Black Vault. As Mr. Greenewald explained, their claim is
ludicrous. "Ancestry.com, and their subsidiary Fold3, has laid down a claim
to copyright on the Project Blue Book material – which has long been
labeled as “public domain” by the National Archives & Records
Administration (NARA). Ancestry.com is claiming ownership to the digital
version of this material – despite me having records that Fold3 doesn’t
even have in their archive and I received under the FOIA starting back in
1996. They simply claimed it was 100% theirs and I was forced to remove it."
Unfortunately, while Mr. Greenewald was completely in the right to post the
public domain documents, the cost of litigating a lawsuit would have been
enormous and for the sake of his family, he was forced to comply with the
takedown request. I was unable to retrieve a copy of the cache from him,
but after some digging I managed to find a copy. It and the other files
have been uploaded to Archive.org and properly marked as being in the
public domain. While the Project Blue Book reports have been uploaded
individually, they have also been uploaded as a single dataset for easy
retrieval and archiving. It's unlikely that Fold3 would try to threaten me
with a lawsuit (though I invite them to try and be laughed out of court),
or that the Internet Archive would cave and remove the public domain
material, but in the event that this happens they will have to file
takedown requests for thousands of items and deal with the certainty that
people have retrieved and duplicated the complete set.
