"One Day In The Life of Ivan Denisovitch" is a novella about the GULAG experience. It's by Akeksandr Solzhenitsyn and gives the flavor of his writing. The GULAG Archipelago is over 2,000 pages, ranges over the whole history of the Soviet Union and its essential, inevitable prison camp system.

@timon_phocas Eh I should have rephrased my question. I meant to say if there are any books in which give detailed and documented information on life in Nazi Germany similar to the Gulag Archipelago books and what you mentioned? Thanks anyway. I'll look into it.

Sorry it's taken so long to get back to you. There are many books about the 3rd Reich. From the prisoner POV books by Victor Frankel and Elie Weisel are very good. At the apex of Nazi government, Albert Speer's books. Rereading "Inside the 3rd Reich" is in my "to do" stack. Geobbels diaries are a POV of a commited Nazi ideologue. I like books by John Toland, he is a careful historian.

@timon_phocas Thanks noted.

If you want something less intimidating than Gulag read, "We the Living," by Ayn Rand.

You’re right. Perhaps the more appropriate term would be a “vital read.”
