Please delete this edition 1979

It's a duplicate to 1979

And make something with the authors :) Thanks

Hi! Author fixed, and edition combined (the ISBN and ASIN appear valid and were added by Amazon in 2023, although the edition isn't available on Amazon any more).

That said, I found the second edition to be a duplicate of the hardcover edition, so I merged it.
