Christian Pietsch

Welcome to my home page at Bielefeld University Library where I work at the LibTec (Library Technology and Knowledge Management) department. Much of what I do is about creating the IT infrastructure for better scholarly communication and reproducibility of research results. Naturally, this won't work without free and open source software, open access, open data, and open research. I am the guy how started this list of alternatives to Google services, and I host the international Open Science Q&A site.
