Have you read the annual reports for the largest commercial scholarly publishers? I have and I hope that you will too. These publishers generously make these key documents freely available on the open web. Here they are for some of the largest scholarly publishers, with a few notes of anthropological interest along the way.

I cannot find an annual report for Sage Publishers. I think that this is because they are not (I think) a publicly traded company. Big news for Sage was partnering with the American Sociological Association to publish its journals beginning in 2010. Sage publishes such anthropology journals as Critique of Anthropology, Field Methods, and Anthropological Theory.
