The dedication of The Ringworld Engineers reads

If you own a first paperback edition of Ringworld, it's the one with the mistakes in it. It's worth money.

What are these mistakes that were corrected for the second edition?

If I remember correctly, the cities that Louis Wu was visiting via transfer booth just before midnight (to keep his birthday going longer) had the Earth rotating in the wrong direction.

    Specifically, Louis Wu is travelling EAST to avoid the sunset -- in later editions of the book, he travels West, which is the correct direction.
