I�m hoping to get some advice on appropriate honorariums to provide to people who work on Open Textbooks. Specifically, I�d like to provide payment to someone to write a chapter for my textbook on a subject I�m not well-versed in, and I�d also like to remunerate two to three peer reviewers of the text.

Does anyone have guidance on respectful sums for writing and peer-reviewing?

Thanks,

Lindsey
