Here's the list (not all were gifts from somebody else!):
R. Jay Magill Jr., Sincerity. Quoting from the jacket: "What do John Calvin, Sarah Palin, Jean-Jacques Rousseau, and Bon Iver have in common? A preoccupation with sincerity. [This is a] beguiling tale of sincerity's theological past, its current emotional resonance, and the deep impact it has had on the Western soul." Looks quite promising.
Dave Barter, Obsessive Compulsive Cycling Disorder. A collection of stories, essays, ride reports, what-have-you, about 10 years of amateur riding.
Tyler Hamilton & Daniel Coyle, The Secret Race: about doping in the TDF.
Andrew Ritchie, Major Taylor: biographical look at one of the early world-renowned bike racers, an African-American from Indianapolis named Marshall Taylor who dominated race circuits at the turn of the prior century.
William Bloch, The Unimaginable Mathematics of Borges' Library of Babel: an apparently (per the reviews) quite readable discussion of the real mathematical intrigue in this Borges short story.
Borges: Selected Non-Fictions. Not sure how much of these I've read, but the price was right.
Borges, Hurly Trans.: The Book of Sand and Shakespeare's Memory. Anybody know anything about these?
