I’ve just checked out Franz Kafka’s The Castle from the library (which I had to request to be brought from storage) and found out that this copy was printed in 1945. It also contained a little disclaimer in the beginning, stating that since paper is a resource useful to the war, publishers then had to use it as conservatively as possible, thus the book itself was printed in the most efficient way possible.
But there is no reason to order new copies. Who reads Kafka, anyway? We need to bring Burger King to Baghdad first. Priorities.
