I found two articles on The Lucidity Institue's website. One by Frederick Van Eeden and another by Stephen LaBerge. They both have sources at the top of the page from another source (editions). How would I cite this kind of source in a speech? Would I mention the website "The Lucidity Institue" or the book?

This is for an informative speech on Lucid Dreaming.

Any help asap would be great. Thanks.
