Fortunately I received this as a gift and didn't waste my money. I am usually a very patient, tolerant individual but it was hard for me not to throw this book across the room. The errors are abundant and many of them could have been avoided had someone proofread the darn book. After having read through the episode summaries I find it hard to believe that Mr. Challen actually watched entire episodes. It wouldn't take more than looking at the list of guest stars to realize that Zoey Bartlet did not appear in "Ellie". I would not recommend this book to serious fans of The West Wing, especially those who are "seriously committed to the idea of 'continuity'."
