We here on SciShow Tangents may have the market cornered on science podcasting, but that doesn't mean we know everything. Put us in a lab, and we're like fish in water! But put us in a library, with all those big tall shelves and the Dewey Decimal System, and we're like a fish not-in-water! So we called in our friend, podcast, theologian, and noted book-reader Vanessa Zoltan to help us learn more about books!

Learn more about Vanessa and her myriad of projects at her website, and follow her on Twitter @vanessamzoltan!
