Publication fees are generally linked to the services you receive. Publication fees have been around for several decades. Originally, in the print world, many journals charged publication fees for full color figures, or for papers that exceeded a certain limit. As an example, you would have had to pay an extra fee if your paper exceeded 8 pages, or contained colored figures. Today, many open access journals rely on publication fees in order to maintain their publishing infrastructure, pay for marketing and distribution of the content, and to cover the wages for the journal’s professional staff that organize peer-review and the editing and production of accepted manuscripts.
