                      of articles and some tweets about Bitcoin came to
                      our attention recently, which led us to do some
                      research into digital currency. Conventional
                      currency (the money in your pocket) is issued by
                      governments, but for some time now there have also
                      been <a
                        href="http://en.wikipedia.org/wiki/Local_currency">local
                        currencies</a> that serve a specific community.
                      Taking this one step further, there have been
                      efforts to create digital currencies that enable
                      Internet payments without a "middle man." The <a
                        href="http://www.openmoney.org/">open money</a>
                      project, based on LETS ("Local Exchange Trading
                      System") software is an early effort. Some digital
                      currencies, such as <a
                        href="http://en.wikipedia.org/wiki/E-gold">E-gold</a>,
                      have been shut down by governments because they
                      were suspected of enabling money laundering. Now
                      comes the <a href="http://www.bitcoin.org/">Bitcoin</a>
                      system, virtual coins in the form of encrypted
                      files that are stored on your computer and can be
                      traded for conventional currency on exchange
                      websites. What does this have to do with
                      libraries? Well... we're not really sure. But if
                      cryptocurrency is about to become the next
                      Internet revolution, we thought we should mention
                      it to you. </p>

                        speculation and hoarding will also cause a
