H-Sci-Med-Tech, part of H-Net, is concerned with the study of "science, medicine and technology across a wide variety of periods and regions of the world. While rooted in history, ours is truly an interdisciplinary field, bringing together complementary theories and methodologies from across the humanities and the social sciences." The site includes, among other features, Resources in the history of science, medicine, and technology.
Librarians at other universities have also compiled research guides for history of science and technology -- for example. the deep and extensive Harvard Library research guide for the history of science at Harvard.
