well
chronologically magicians nephew is first but the order they were released in was:
the lion, the witch, and the wardrobe
prince caspian
the voyage of the "dawn treader"
the silver chair
the horse and his boy
the magician's nephew
the last battle
and it kind of ruins it (for me) when magicians nephew is first and horse and his boy are third, because #1 those are like the two worst stories and #2 horse and his boy is actually set DURING the lion the witch and the wardrobe so its like wtf why not just edit it so that that story is in the middle of it while you're at it jerks
