German schools do not always have a library. Some better schools have (e.g. my school, founded in 1543); instead of librarians a teacher is detached to do the library work in his spare time. So was my grandfather (Latin, history), one of his pupils as a teacher at the same school (Latin, Greek), and now it is worked by a neighbour of mine (mathematics, biology).
We have two departments at the library:
For teachers (with some rare and expensive books, too), and
for pupils a stock of schoolbooks for every class which are leased free for the duration of the term.
By the way - are you the Sarah I met at Barrows upon Humber, or not? Discuss.
