Separate this two editions (they are different books)

[Jorge]

This two books are listed as two different editions of the same books but I believe they are two different books altogether.

The Brain was published in 1980 and has 149 pages and among the papers included inside there is one by Francis Crick titled "Thinking about the brain".

The Scientific American Book of the Brain was published as a 1st edition for the first time in 2001, it's much longer with 356 pages and Crick's paper is nowhere to be found (there is another one by him in there, but different paper).

Looks like someone got this for you.

Hello,

I am not sure if I will be able to explain accurately.
I have two books of different genre and 3 editions of the first and 2 editions of the second.

I made a mistake while trying to combine the editions, I combined the editions and my second book under one edition.

Here are the links.

Under this, you can see editions of my first and second books.

Would anyone be possibly able to separate them?
