The Netlib email server software is available from the Netlib repository itself. The software provides mechanisms for processing user email requests, which may involve keyword searching and file retrieval. Slightly modified versions are in use to distribute statistical software from statlib@temper.stat.cmu.edu and by the TeX User Group to distribute TeX-related software from tuglib@math.utah.edu. Appendix A lists a selection of Netlib sites and sites running the Netlib email server.
