Where Is All the Book Data? - Public Books

After the first lockdown in March 2020, I went looking for book sales data. I'm a data scientist and a literary scholar, and I wanted to know what books people were turning to in the early days of the pandemic for comfort, distraction, hope, guidance. How many copies of Emily St. John Mandel's pandemic novel Station Eleven were being sold in COVID-19 times compared to when the novel debuted in 2014? And what about Giovanni Boccaccio's much older-14th-century-plague stories, The Decameron? Were people clinging to or fleeing from pandemic tales during peak coronavirus panic? You might think, as I naively did, that a researcher would be able to find out exactly how many copies of a book were sold in certain months or years. But you, like me, would be wrong.
