Most of us are familiar with the pressures of "publish or perish." So what do you do if the journal in which you wish to publish your scientific articles tells you it won't publish your article unless you give it something extra of value? We are all familiar with the practice of "page charges" and the resulting disclaimer at the bottom of the title page identifying some research articles as paid advertisements. Two other charges that authors are now sometimes expected to pay to have their articles published are "warranties and indemnification" and "copyright transfer." Like page charges, these charges involve giving your publisher something of value as a condition of publication, but, unlike page charges, they cannot be funded by your research grant. They could come out of your own pocket, and they could be very expensive.
