The Bay Area is flush with good used bookstores, but that doesn't change the fact that there's nothing so tantalizing as a well-stocked private collection. If you've ever ducked out of a party to eye the host's shelves, or peered through the street-level windows of a stranger's study, you'll want to check out SwapSF's Book Swap, a bibliophile's delight featuring 10,000 square feet of volumes up for trade. The choice of libations should satisfy both sharp-eyed seekers (free Meth coffee if you bring your own cup) and mellow browsers ($1 beer and wine).
