I have for sale a great 7 book series of the "Greenwood Guides to the Universe". All books are in excellent as new condition. For further information check out sites such as
https://www.librarything.com/series/...o+the+Universe
and Amazon.com.
The price for the set is $70 plus post to your post code. Individual books will be $15 each plus post.
I would prefer to sell these as a complete set, however I will consider selling individually if there is no interest in the complete set. The shipping weight will be about 5 kg and volume about 27 x 18 x 16 cm.
