    Abstract
    Variables measuring the nature and level of Internet usage by natural scientists improve the explanatory power of a traditional bibliographic model of scholarly productivity. The data used to construct these variables come from log files generated by the internal accounting modules of the UNIX operating system. The effects of Internet usage on productivity are quntifiable, and it is possible to calculate tradeoffs between Internet usage and the more traditional inputs
