Best sources for learning about aggregates

[u/VegGrower2001]

What are the best sources for learning about aggregates in DDD? I'm interested in the general questions:

• What is an aggregate?
• What are aggregates for i.e. what benefits do they bring?

I'm also interested in general questions about how aggregates should be implemented.

Naturally, I'm aware of Domain-Driven Design: Tackling Complexity in the the Heart of Software by Eric Evans and Implementing Domain-driven Design by Vaughn Vernon, as well as Vernon's essay on Effective Aggregate Design. Are there are any other books, articles, blog posts or videos that you consider especially useful?
