Abstract: Computer science is a relatively young discipline combining science, 
engineering, and mathematics. The main flavors of computer science research 
involve the theoretical development of conceptual models for the different 
aspects of computing and the more applicative building of software artifacts 
and assessment of their properties. In the computer science publication 
culture, conferences are an important vehicle to quickly move ideas, and 
journals often publish deeper versions of papers already presented at 
conferences. These peculiarities of the discipline make computer science an 
original research field within the sciences, and, therefore, the assessment of 
classical bibliometric laws is particularly important for this field. In this paper, 
we study the skewness of the distribution of citations to papers published in 
computer science publication venues (journals and conferences). We find that 
the skewness in the distribution of mean citedness of different venues 
combines with the asymmetry in citedness of articles in each venue, resulting 
in a highly asymmetric citation distribution with a power law tail. Furthermore, 
the skewness of conference publications is more pronounced than the 
asymmetry of journal papers. Finally, the impact of journal papers, as measured 
with bibliometric indicators, largely dominates that of proceeding papers. (C)
