How do you gain access to more information about The Spalding Foundation founded by Baird T Spalding's great grandfather and publication of their research work?

There was no Spalding Foundation. Spalding's novels are fictional according to his biographer.

Is there a link or something of the sort where we can read this and not just take your word for it? What you're stating goes against 6 volumes of work from Spalding attesting to these expeditions being legitimate and accurate. His publisher, DeVorss, also corroborates his studies, along with everyone else on the expedition. Some of us seek to find the answers to these things and not be shut down immediately by unfounded skepticism that doesn't seem to have a source. Please advise.
