A general simple small book on memory Its so Ibrahim Faqi's type The one star plus was because his wife printed and finished his book after his death!
Recommendation: if you didn't read about memory before you & don't have the time to read large books,Its good to start and see if you are greed for more depth like in my case
If you are a reader you can easily Speed read it and get the most of it and start another book on memory in english
