There is a company named DL Consulting based in Hamilton, New Zealand that is behind the website and company known as VeridianSoftware.com. Here is an explanation of the company from their website:
Since 2002 DL Consulting has been helping libraries around the world retain their position as critical and important community resources. We understand that libraries are responding to an increasing demand for online access to content. Our Veridian digitization services give libraries the ability to preserve archives of historic material and deliver the content as a digital collection to their communities.The company focuses primarily on newspaper collections and does not merely facilitate their digitization, but also has a substantial online collection of newspapers from around the world.
In addition, the company maintains a general search engine specifically targeted at digital newspaper collections called Elephind.com.
You can see from this screenshot that Eliphind.com searches 2,652,049 newspapers from 2,705 newspaper titles. This comprises millions of pages in Australia, New Zealand and the United States as well as other countries.
I view this as an example of the reason why I say you cannot have ever searched all the online resources. I have mentioned this website a few times before, but almost never see it listed in resource lists from the genealogical community. We mostly have blinders on when we look at online resources. It is time to take off the blinders and realize the vast amount of information that is out there waiting to be researched.
