Subscribe to Open

The following IWA Publishing journals are now Open Access via a Subscribe to Open (S2O) model, increasing the impact of water and wastewater publishing around the world. 





What is Subscribe to Open?

Subscribe To Open (S2O) is a collaborative Open Access model that relies on subscriptions to make content Open Access without the need for author fees. The model converts subscriber-only access to IWA Publishing journals to Open Access using existing library relationships and subscription purchases.

Because journal costs are sustained through S2O subscriptions, authors are not required to pay article processing charges in S2O journals. As long as S2O subscription revenues are maintained each year, journals will be published Open Access and up to five years’ historical content will be made freely available.

The process:

  1. Customers are invoiced for journals in the Subscribe to Open program, processed in the same way as their regular subscription.
  2. If enough customers commit to Subscribe to Open such that sufficient revenue is raised to support journal costs, etc., all journal content for the next year is published Open Access and the paywall on all previous volumes for the last five years is removed. 

Supporting Subscribe to Open

Open Access to S2O journals for 2021 is possible thanks to the overwhelming support of our global community of institutions, organisations and individuals who gave individual support for S2O or renewed their journal subscriptions as S2O subscriptions for 2021.

By Subscribing to Open, everyone benefits – with access to all IWA Publishing journals and unlimited Open Access publishing.
