> A few of the selected findings:
> -- When ranked by Impact factor in their respective categories, OA

> -- The study suggests that OA journals have a broadly similar citation
> pattern to other journals but may have a slight tendency to earlier
> citations (pg. 6)
> -- The wide distribution of these OA journals has not yet been shown
> have any appreciable effect on their appearance in lists of cited

> The study, apparently part of an on-going analysis, provides credible
> grounds for discussion about Open Access.
