How do you find good scholarly criticism of a book?

When I read a book with new and interesting ideas, I usually want to know if there are major flaws that any knowledgeable scholar in the field would point out immediately (Two recent examples are Pinker’s “The Better Angels of our Nature”, and Harriss’s “The Nurture Assumption”)

I usually:

  • Look at reviews on Amazon (especially the negative ones)

  • Google with keywords like “criticism, “review”, “problem”, (and whatever major issues I seem to have run in) etc.

  • Search Google Scholar for the same thing

  • Ask in some communities (LessWrong, reddit AskHistorians) if anybody read it

One problem is that I end up spending a lot of time reading stuff of no interest—either reviewers explaining the book to people who haven’t read it (and sometimes even misrepresenting it’s arguments, or framing them in terms of their pet controversy), or bloggers/​posters who haven’t read the book so go off a summary and come up with arguments that are already well-addressed in it.

So, what tips and strategies do you have for finding solid scholarly criticism ?
