How to track the papers that cited one specific paper
Google Scholar is one of several repositories that has such a citation graph (and I find it the most straightforward for doing the task you are suggesting).

Every entry in Google Scholar that has been cited and had those citations tracked in Google Scholar comes with a "Cited by N" link; clicking that link gives you a list of all of those citations.

You can also search within those citing articles.
