I once worked at the library of a university. Part of my job was to check the catalogue against the actual bookshelves to make sure the books are physically present.
So I got to social science section. In particular the Communist Manifesto by Karl Marx.
Now this is an national university with >170 years of history. The spreadsheet in my hand showed that there should be 9 copies of the 1908 edition on the shelf.
I found none.
Every copy has been stolen. The irony of this is just too much. Communism supporters stealing from the general public to satisfy their personal desire of collection.
Aside. A regret I have was not checking out 'The Hitler Youth' at the same time. Although I suspect the university might have removed them from the shelves.
