These summaries are fantastic. I have several friends who don't have the time / patience to make their way through 1800 pages. But they can make their way through a series of short executive summaries, and if they find something particularly interesting they can look up that particular article. It's also useful for me to be able to quickly look over a summary before and/or after I've read the whole article. I'd highly recommend that these summaries or something like them be included in future versions of the book.
