SDZ stands for Sprachdidaktisches Zentrum (at Pädagogische Hochschule Freiburg im Breisgau), Germany. SDZ-Informationen is a series of 1980s and 1990s booklets for teachers about teaching English (and for other subjects). I have posts of most of the TV series, some others, I previously didn't know at all. Not sure if all of them are real TV series or just school books. Needs further inverstigations.
The publishing years are often several years later than the TV series. Google is a poor source. Next to worldcat, there is d-nb.info, where for some of these (and other) books, there's at least a table of contents.
