Please fix author name and combine author pages, and fix title casing

[Jackson]

The editions of this book have different authors but they seem to be typos.
Here is an example of a correct one:
https://www.goodreads.com/book/show/5...

Here are ones where the author has a typo in it:
https://www.goodreads.com/book/show/5...

and
https://www.goodreads.com/book/show/7...


In addition, the casing on this title is incorrect:
https://www.goodreads.com/book/show/5...

It should match this casing which is correct:
https://www.goodreads.com/book/show/5...

Thanks very much!
