Query: amazingly superficial and disappointing

In this book she covers what seems the entire history of influenza, which includes the greatest pandemic in history in 1918-1919, the swine flu scare in 1976-- she even goes into litigation over the vaccine-- attempts to dig up bodies killed by the 1918 virus and sequence its genome, none of it in depth. In all of the footnotes for this book, there is not a single one for a primary source regarding the pandemic itself. No diaries, no lab notes, no original letters. There's hardly a reference to a contemporary newspaper. In fact, her notes cite interviews with a historian who wrote about the pandemic. Gina Kolata is a reporter, and this is a glorified newspaper story, expanded. Too bad. The subject itself is of interest.
