Well, actually 1 shelf from my office, and a large pile of books on the floor for which there is no shelf space.
Many of the ones on the floor are pretty recent, acquired from various catch-a-catch can sources in what masquerades as bookstores here in Porterville: the local 99 cent store, the occasional find in a thrift shop, etc.
You can find lots of fun stuff, modern math and algorithms at the heart of the most innovative applications on the internet, technical manuals, hiking books, marketing, psychology, interpretations of current events, and film finance.
If you find any of it interesting (and you will!), simply click on the book and order immediately from Amazon and you will have it in your hands in just a few days!
