If you’d like something not connected to charlatinism, look into the work of Ian Stevenson, a Psychiatrist at the University of Virginia School of Medicine.
He was director of the Division of Perceptial Studies until his death in 2007.
And that section is doing ongoing studies on the paranormal, particularly the possibility of reincarnation. So, they’ve written quite a bit about the subject.
Stevenson himself authored two books and there have been books published regarding his efforts and research.
Even tho his work was polarizing, Stevenson was respected by his colleagues. Some found his work compelling while others felt he was gullible.
You can draw your own conclusions. But at least the Univ. Of Virginia is a reputable place to start.
If you want a general outline, the Wiki article on Stevenson is quite thorough and a good place to start and then you can proceed to the website for the University’s School of Medicine and the Division of Perceptual Studies.
There are a number of books listed in the article and in all likelihood could be available through your local library.
BTW: Even tho he was with UVA for over fifty years, Stevenson was originally a Canadian.
