Instructional Booklet for Planet Earth

Sometimes I'm grateful for Wikipedia's articles on really basic things; other times I think it sounds like it's written for aliens who have just landed on earth but can for some reason understand English and use the internet.

Yesterday I needed to know when spiral-bound notebooks were invented, and in my search I of course came upon Wikipedia's article on notebooks. It included the following gem of wisdom: "It is frequently cheaper to purchase notebooks that are spiral-bound, meaning that a spiral of wire is looped through large perforations at the top or side of the page." So, aliens, once you have assumed human shape, gotten a job, and earned some money, and would like to know which kind of notebook would be most economical to purchase so that you can afford to take as many notes as possible on the weaknesses of the human race and how to thrash us, here is your answer: the spiral-bound kind. And we have provided a description so that you'll know it when you see it.

Also, aliens, ballpoint pens won't work in outer space, FYI. Fortunately we have invented a pressurized space pen that should do nicely. That's right, we're always thinking of your welfare. Please don't hurt us.
