Independent, membership libraries like Folio were really the first broadly accessible libraries. They trace back to one started by Ben Franklin in Philadelphia in 1731 so that bookworms of modest means, like young Ben, could have access to important books. Today, they provide places "to be alone but not alone" -- sociable, booklined "jewels of a perfect size" where booklovers can work in quiet, talk about ideas, and hear stimulating programs open to the broad community. Rather than relying on taxpayer support, these libraries charge modest membership dues and receive tax-deductible donations of fine books.
