Vivian Marquis and Patricia Haskell,
The Cheese Book 1966
I was in my kitchen looking on a high lonely shelf, right to the ceiling, and came across a big pile of dust-covered books and papers. I dug around it, and it was mostly junk, but lo and behold. At the bottom of the pile lay this beauty. It was published in 1966, and it looked like it hadn't been touched since that year.
I love cheese, and had just finished a few books, so I thought I would give it a try. The book takes a few chapters to talk about the history of cheese making, how it's made, and a chapter on etymology. After that is 14 chapters on specific cheeses. Their taste, their looks, the texture, anecdotes, history, availability in the US (circa 1966, of course). Honestly, it's quite good. Not sure where it came from, but I'm glad I found it.

John P. Parker,
His Promised Land: The Autobiography of John P. Parker, Former Slave and Conductor on the Underground Railroad
This is exactly what the name says it is. It is a history that could have been lost to time had it not been for a journalist who heard rumors of the man and interviewed him in his old age, soon before he died. I'm actually rereading this. Highly, highly recommend this for anyone interested in human rights, slavery, or the Civil War.
