The philosophy of science concerns itself with fundamental questions related to science, such as what is - and is not - science, the reliability of scientific theories, and the purpose of the scientific enterprise. The PhilSci-Archive archive, hosted by the University Library System of the University of Pittsburgh, is an electronic collection devoted to the rapid dissemination of contemporary philosophy of science. This means users are presented with the most cutting edge articles in the form of preprints (early versions of works that have yet to be peer reviewed). Readers may search the archive using a variety of categories, including subject, year, or even conference. If unsure where to start, the Latest Additions section can be quite enticing. Here readers will find the most recent submissions to the archive, which, at the time of this writing, included Joshua Rosaler's "Local Reduction in Physics" and Sally Shrapnel's "Discovering Quantum Causal Methods."
