You can find my look at BookScan 2008 right here.
I'd strongly suggest grabbing the chart and saving it off before Jonah gets a C&D. Tomorrow will likely be too late!
Interested in your thoughts, as always!
Edit: Tom Spurgeon has some good comments here. For the record, Tom is 100% right: look at these with a grain of salt, then a chunk of salt, then an entire salt mine, because, at best, these numbers are just the visible tip of the iceberg.
I really really tried to make this clear throughout the piece: go and count how many times I say something like "to the stores that report to BookScan" or words to that effect. I keep being afraid that I'm hurting the readability with all of the ass-covering I do!
