Self-Selected or Mandated, Open Access Increases Citation Impact for Higher Quality Research

Figure 6

Distribution of Journal Impact Factors by Journal.

As with the distribution of individual article citation counts (Figure 3), the distribution of journal impact factors (average citation counts) is highly skewed.
