We passed by Humboldt University last month and saw what seemed like a flea market for books. We found out they were selling old books at low prices. We could have bought some, but the problem is, the books were in Deutsch. They were probably old stocks from the university’s library.
These pictures were taken a month ago:
And this one was from the weekend: 
*Humboldt University in the city’s oldest university founded back in 1810 by by the liberal Prussian educational reformer and linguist Wilhelm von Humboldt . It used to be named as the University of Berlin and was later on changed to several other names: Frederick William University and Universität unter den Linden and finally it was named in honor of its founder.

I always loved going to the book sales at German universities. So many good deals on good books. But ours were usually in the cafeteria =D.
Hi! Nice input. Keep it up.
