The best way to know for sure is to actually ask the seller. When there was another source being discussed, I simply sent the guy an e-mail. He replied to my question about was it a Yamaha authorized product. His reply was a simple: NEGATIVE.

We have had some activity from members sharing you as a source for
discounted, factory service manuals.
Because we are always concerned about being a good "partner" with the
community we have established a policy that prevents anyone from helping
those folks who have been selling digital copies of factory Yamaha
manuals because, to the best of our knowledge, Yamaha has not authorizedthe for sale to non-dealerships.
What I am trying to ascertain is if this is a Yamaha authorized product
so that we can continue to support the public posting of it as a source.
With our high visibility to Yamaha and the community at large, we can't
risk running into problems with protected Intellectual Property or
Copyrighted material.
Will you please confirm that these products are not going to land us in
hot water with Yamaha?
Thanks in advance. I'd much rather contact you directly than ask Yamaha
and possibly create an issue between you and them.
