All you need to get going is ‘Go, A Complete Introduction to the Game’ by Cho Chikun and ‘Graded Go Problems for Beginners Vol1’ by Kano Yoshinori.
Later ‘Fundamental Principles of Go’ by Yilun Yang is excellent for adapting to the full size board and general improvement.
By comparison I found the ‘Learn to Play Go’ series very disappointing, inefficient and cumbersome. Not user friendly. Fortunately it was free with my 2nd hand board.
I haven’t seen the ‘Level Up’ series. It looks interesting but perhaps its format makes it overpriced?
