From a book review

[Poetlister]

Scientific accuracy appears to be rather patchy, with much of the content having been extacted from Wikipedia, re-worded in part, and occasionally misinterpreted somewhat.

"Dawn of Small Worlds: Dwarf Planets, Asteroids and Comets" by M. Moltenbrey. Reviewed in The Observatory, 2017 February, page 28. Comment is superfluous.

[Zoloft]

The book is being criticized in other reviews for poor grammar and uneven writing.

If the book really does contain content lifted from Wikipedia, it probably shouldn't be cited as a source in the Rosetta (spacecraft) (T-H-L) article.

That would scarcely be the first time something like that has happened. There is even a name for the phenomenon: citogenesis.

[The Garbage Scow]

It's marginally better than those sham "publishers" who lift the Wiki article text wholesale (including typos, bad formatting, and vandalism), bind it and sell it on Amazon as a book with a bunch of fake authors listed.
