Nowhere is the potential for online philanthropy more evident that in the first flush of the public response to September 11th. All told, figures indicate that more than $70 million of the $676 million in contributions pledged in the first 3 weeks after the attacks were given online. The example of two organizations is particularly suggestive of the Internet?s ability to facilitate giving. The Red Cross (the largest single recipient of funds) received $60 million through online donations, which accounted for almost 30 percent of the total raised by the organization during those first weeks. Similarly, of the $1 million raised by Catholic Charities USA, almost one-third of the donations was made using the organization?s website. Significant online donations have also been given to the newly created September 11th Fund and the Salvation Army. Online giving has soared ? indeed the server of at least one charity had difficulty keeping up with the response. Whether "e-philanthropy" will continue as the preferred form of giving for so many donors remains to be seen, just as it remains to be seen whether the world-wide outpouring of charitable and voluntary action in response to September 11th indicated a new level of sustained civic participation. Regardless, this use of the Internet signals the great potential of Information Technology ? a potential that this guide is designed to tap.
