A LOT of them. My brother sends me a copy of just about every one he gets.
Most are saved in a Google Drive folder that I can share if anyone is interested.
Almost all of them are non-fiction and are on a range of topics. Examples:
1001 Fact That Will Scare the Shit Out of You
America Aflame - How the Civil War Created a Nation
Curtains: Adventures of an Undertaker in Training
Deadly Choices (about the anti-vac movement)
Silver Like Dust
And many many more.
