Typical so-called Mandela effect pap!

I remember reading about the kid napping from in depth articles back in the 70's.

What you are trying to capitalize on to support your "agenda" is simply something that is the nature of the internet. Simply put most articles and books "pre-internet" have not been digitized and are not available on the internet.

A great example of this is the Library of Congress. The vast majority of what is catalogued is not available for download.

Other publications such as magazines and newspapers no longer in business don't have readily available archives.

Some newspapers don't have digitized archives and must be viewed in person.

I research a lot of obscure topics and run into these issues all the time. Finding the info turns into a lot of real footwork and knowing where to look. This process by the way is how authors bring fresh material to light. You think it just magically appears on the internet?
