EDP Sciences presents a new model where the author chooses their own fair price to publish an article in Open Access (OA).

The Liberty APC model means that authors can choose from a number of options, the level of article processing charge (APC) they will pay to publish their article - including an amount of 0€ in 2016. It is expected that they will investigate all options for funding, for example from their funding body, their institution or their organization, but ultimately it will be their decision how much they feel is a fair price to pay.

Liberty APC is a useful model for journals at launch stage and for the first years of publication. It provides a useful gauge of a journal’s value before it is indexed, as all authors who have a requirement to publishing Open Access can publish in a journal relevant to their research regardless of access to funding.
