Thank you, NJ.
The problem is that I was not careful and added some non core libraries to "Libraries" folder. That is what I am trying to clean up - move additional libraries out of the Libraries folder and put them in my Additional Libraries folder. So, I still want to see a list of the core libraries, and I cannot find one.
And I just subscribed to the 30 page thread, Subscribe to library updates.
Best regards.
Sandy
