|Confirmation of the
impact-enhancing effect of self-archiving in physics, using the ISI database
t count citations, and comparing articles from the same year and journal that
were and were not self-archived in the Physics ArXiv.
|The effect is even bigger
than in computer science, especially more recently, and within 2-3 years of
publication (see 2001; 2002 is being analyzed now, more results soon).
