The Chronicle: 3/25/2005: New Study Compares Open-Access and Traditional Publishing

Reg. Req. The Chronicle: 3/25/2005: New Study Compares Open-Access and Traditional Publishing: "The first large-scale comparison of open-access journals with traditional journals reflects a publishing industry in flux.
...
Some of the findings were not surprising: Compared with traditional journals, open-access journals were by and large newer; they printed fewer features like editorials and news articles; and more of them finished the previous fiscal year in the red. Open-access journals also received fewer submissions and were less selective in choosing among submissions.

But other results were unanticipated. Contrary to expectations, author fees were charged by a larger fraction of traditional journals than open-access journals."
