Collector F. M. da Costa has an amazing Flickr page where he opens up his games, showing everything that came in the box. It's very pretty just to look at, but it's also a timelapse, showing the slow and steady decline in the number of pieces of paper that shipped alongside a video game.
Some of the older games came with all kinds of stuff. Fast-forward to the Vita and you wonder why they bother putting it in a case at all.
You can see Costa's complete collection at his Flickr page.
