Looking for model profiles that make a good use of Sources

In the profile, I think "About" should be reasonably brief, maybe 3 or 4 paragraphs, and should not be a copy paste from somewhere else. That's my personal view.

I think sources should either be directly referrable on the site or have a link to somewhere not behind a paywall where people can read the original documents.

I am looking for profiles which provide a good combination of a good about summary combined with links to sources that I can use as a best practice or model for my work.
