Books
There are many books available about the subject of the NDE. My recommendations are based on personal experience. I had a near death experience in 1978 and again in 1988. After my experience in 1988 - I read as many books on the topic as I could find. I needed to put my experience in perspective. The one person who captured the essence of the experience first hand was Carl Jung. These books reflect the cream of the crop in my opinion.
