Neil Gaiman wrote a really interesting blog on the process of getting his book American Gods published. It was so popular that the blog was actually the main component of his book Adventures in the Dream Trade, which is where I first read it. He was basically talking about, ok the book's written, what happens now before it ends up in a bookshop and it was pretty fascinating!
I was thinking that blogs could be used to show people, staff and the public, all kinds of behind-the-scenes stuff and give them an insight into what goes on to actually get various library things up and running. Also it might give them a chance to comment or make suggestions.
The American Gods blog still exists on Neil Gaiman's site, which is well worth a look, and in checking that it was still there I discovered that to celebrate the 7th birthday of the blog a poll was held to find out which of his books should be posted online. Now you can read American Gods free on the web, how's that for the power of the blog!
Also, Neil Gaiman has a sock monkey which you can view in Sock Monkeys: 200 out of 1,863. :)
