About maybe 15 years ago, here in Germany (probably existed in other countries, too, but I don't know for sure), there was a Star Wars collection. I don't know how to name it otherwise. It was something where you subscribed to a magazine and got weekly issues with some pages, which you could collect in given folders.
I think it was officially licensed stuff. It contained a lot of information about the stories happened in the movies, but also about planets, species, technology and also a lot of information which is now considered EU, like things that happened long after ROTJ. It also had a lot of very detailed blueprints of ships, crafts and weapons.
I don't have those old folders anymore, and they were not complete back then (still I had 3 or 4 folders with estimated 300 pages). I want to see if I can find this collection somewhere online or in physical form, but I don't know what to look for other than "Star Wars Collection". Maybe someone knows what I mean and can give me additional information about it.
I know that I can probably find all information I ever wanted to know about Star Wars in some Wikis, but I liked that collection.
