It would be great if each topic displayed information about which CSP specs it appears in. This would ensure that when topic Foo is updated or altered, we know to rebrew each book that contains topic Foo without having to search for the topic in each relevant book. This would probably be super helpful as we expand the set of books for each product using Skynet.

Additionally, this will help in topic reuse across products so that if I am making improvements to a topic, I can contact someone who is using the topic for another product's documentation and warn them to update their docs.
