How do I show latest DCR of a specific type

Denise Bowker

I'm sure it's in some manual somewhere, but damned if I can find it.

I would like to display "the most recent" DCR of a specific type. For example, press releases are issued all the time.
I'm looking for two things:
1) I want a component to display the most recent one.
2) I want to create an index page of the 50 most recent ones.
