If you read the second paragraph of the product description:
Project Webster represents a new publishing paradigm, allowing disparate content sources to be curated into cohesive, relevant, and informative books. To date, this content has been curated from Wikipedia articles and images under Creative Commons licensing, although as Project Webster continues to increase in scope and dimension, more licensed and public domain content is being added. We believe books such as this represent a new and exciting lexicon in the sharing of human knowledge.
Basically it's saying they took information you could easily google, bound it together and are selling it because they found a market that's hungry for information and they think they can sell it in book form. If you look at this seller's other listings the range of content/topics is suuuuper vast but they all have very similar covers / listing format. It looks like some kind of a mill setup, if it's not actually entirely automated. I could be wrong but that's my impression./
Has anyone here actually purchased the book?
