Subscription or dues income helps each publication covers the costs of production and supports continuing improvements to our online systems. Most of the societies, associations, or academic departments that sponsor these publications also depend on this income to support conferences, travel grants, awards, and other activities.
We continually explore other funding options, including grants, bequests, institutional subsidies, and endowment funding as alternatives to subscriptions or dues income. We are open to exploring any arrangement that would allow us to make publications accessible without subscriptions or dues payments, as long as this can be done in a sustainable manner without harming the journal or its sponsor.
