This is a much more useful comment than the OP.

Books need review - not just a few comments on the general concept, but line by line proofreading of the English, and fact checking of every single technical statement.

This is fundamental to the process. It's not an aspiration, it's part of the writing process - because often you'll be writing content while other content is being reviewed, and feedback from both can influence the rest.
