Clarification about the license is needed

In the web www.MooreGoodIdeas.com said that the license of the library is BSD. But BSD is a family of licences not a license itself. Which type of license hat the component?: original "BSD License" or BSD 2.0 or other. I don't see in gitlab any reference to the license of the library.

Thank you very much! I need this infomation for the attribution process.
