If anyone is interested in the history of the camp and prisoners then they should get a copy of If This Is A Woman by Sarah Helm, one of the best books relating to a specific camp that I have ever read.
It's a definite must read before ever visiting the site otherwise you would miss out on some nearby sites that are linked to the camp but quite unknown about.
I’m reading this and have to agree, excellent researched book not an easy read in places but that’s the point...
