Prison Architect has multiple versions available on Steam and I'm wondering which edition I bought when I bought it. Through the DLC menu in the game's properties I can tell I have at least Aficionado, because the list of owned DLC contains both the soundtrack and art book from that edition. I also have all the games listed in Introversioner, but is there a way I can confirm? Perhaps the biggest question is whether or not I have the Name in Game edition, because I can't think of a way to check that.

The last time Valve made Portal free, it was identical in every way save one: You couldn't get the Source SDK with the free version, which you need to play mods.
However, Valve used to give you the SDK when you purchased Team Fortress 2, which is now free to play, so that may have changed.
As of the Steam Discovery Update on Sept. 23rd, 2014, Steam itself now shows you the DLC you own in the Store page without having to use browser extensions or look at the game properties in your library.
The blue markings on the left side of each DLC entry indicate that I own it already and if I hover over it, there will be a popout that shows that it's in my library.
Note that isn't perfect. In this particular example, Steam shows that I don't own Wonders of the Ancient World, even though I do, but I'm guessing that's a problem with that particular piece of DLC, as it's done that since release. However, Steam still won't let you buy anything you already own, so you're safe from double purchases.

I found the answer: Steam Account Information
You can find all your past purchases including their names on the account information page, and in my case the list contains "Prison Architect Introversion".
