After HaPoC-I held in Ghent in 2011, two Special Issues went into preparation to collect refereed contributions to the Conference and some additional contributions. The paper to be collected in the first of these issues were already published online on the website of Philosophy & Technology (Springer) for a while. Now the introduction to the same volume has been published and it is available at http://link.springer.com/article/10.1007/s13347-014-0169-4#. The bib entry is also available under our Publications tab.
