Which organization is responsible for the information?

Sometimes a URL can give you a clue, as was mentioned in the section about Authors. Serious organizations often present themselves clearly and are keen to make it easier to contact them.

Is it a private person and not an organization?

Many private people have ambitious and serious web pages with factual and correct information. It is important to think about evaluating these critically to understand what it is that has been published and why.
