Rosa Luxemburg
This book was first published by Oxford University Press in 1966. The OUP paperback, which is stated to have been the "abridged" version, was published in 1969, and this Schocken version in paperback was published 20 years later.
There is an Introduction by Hannah Arendt.
The book itself is a 500 page closely printed tome, so we dread to think how long the unabridged version was!!
