Yeah, I would still recommend getting the pre-New 52 stuff (and Thunderworld and Convergence), but if you want to check out the New 52 version, depending on where you are, library would definitely be a great idea to get to find it (and other Captain Marvel collections you may be interested in). Most cities have websites where you can check and see if they have what you're looking for in the library you're interested in, so I would check that out for your local one and those in neighboring cities.
