Today you might be in an adventurous mood. Put that creative spirit to good use by going a search-and-explore mission to your local library. More than 3. 1 billion books are purchased yearly in the united states. Many of those books are made from non-recycled paper and petroleum-based inks. Do you part by getting a library card to check out the latest books. Libraries often sponsor book clubs so you can bond with fellow bibliophiles.
