Anyway, the final words in this book are about Wikipedia. I commend the author for noting that
I cannot deny that I have dipped my toes, and sometimes both feet up to the knees, into the unruly waters of Wikipedia. This is a vast and growing resource, which is very uneven, not always to be trusted, but which is full of many fascinating articles and leads.
Indeed! Wikipedia is a friend...the kind that is tons of fun and knows a lot, but you still have to keep an eye on.
