Mathematische Schülerbücherei some questions

[joeres]

Unfortunately, I can't remember on the book series "Mathematical Student Library".

At the time, however, I always enjoyed reading the math school magazine "alpha". At https://mathematikalpha.de/alpha, Mr. Polster has made the magazine available as PDF files. Even his math program got the name "alpha" from this magazine.

He also made books, other magazines and texts available as PDF from that time:
- Math problems: https://mathematikalpha.de/mathematikaufgaben
- Mathematics booklet "Unterhaltsames Mathe-ABC": https://mathematikalpha.de/lvz-mathematikhefte
- Mathematics school books: https://mathematikalpha.de/mathematikschulbuecher
- Mathematics books: https://mathematikalpha.de/mathematikbuecher
- Math texts etc .: https://mathematikalpha.de/weitere-mathematiktexte

I can still remember a lot of it (e.g. the book "Der Señor und die Punkte" and "Über Zahlen und Überzahlen") very well. For me one of the most interesting sites on the net. Maybe it will help.
