When it was announced in 1997, Bill Gates' library philanthropy programme attracted a tremendous amount of media attention. A central feature of that coverage was a renewed interest in Andrew Carnegie's library building programme. While identifying the historical similarities between Carnegie and Gates is an interesting exercise, failure to ground these comparisons in a critical policy analysis frame that attends to the political economy of largescale private philanthropy seriously limits, if not jeopardizes, the public library community's ability to respond to the broader cultural implications of Gates' library programme. Here, the radical philanthropic approach is used to frame a historical analysis of Andrew Carnegie's philanthropy as a response to the contemporary class warfare of the period, within which he was deeply implicated. Unpacking Carnegie's library philanthropy for its ideological importance in the struggle over the ownership and control of the means of industrial production provides a powerful analytic lens through which to view capital's updated hegemonic project, as reflected in Gates' philanthropy, which is designed to bring software and internet connectivity to America's public libraries.
