An easy way to keep track of this data, I've compiled a google spreadsheet of each item that you can pick up and examine. Not all of them are readable (The teddy bears are most likely not necessary for the achievement), but I figured we can be safe rather than sorry.[docs.google.com] For the readable items, I recommend pressing 'T' to read every side of the object if possible. I don't know if this is necessary, but again, safer than sorry.

You can find which room you are in by pressing 'Escape' and looking at the top of your menu, where it will say something like "Int. [ROOM NAME] - Night". Use this to reference which room you are alongside the guide.
