As time advances, and old generations die away, history becomes distorted through the filters of the current generation. Books such as these reflect real events, real attitudes, real people who dealt with the unthinkable to the best of their ability at the time. It's easy to misjudge the past from our vantage point and those things we think undesirable we deny or ridicule.These books should remain accessible to all to remind us of these facts. We need to remember that what is real for us today may not be believed in future decades either.
