Autobiography of a Yogi book?

Question

I checked my library and looks like there are many different versions of the book, or many books with same title.
Please, if you're familiar with the 'main one' please share author and date of book.

Many thanks

'In 1946, Paramahansa Yogananda (January 5, 1893 – March 7, 1952), published his life story, Autobiography of a Yogi, which was instrumental in introducing the ancient science of yoga and meditation to the West."
