This article provides a brief description of the landscape of open access book policies in the European Research Area (ERA), that include funding mechanisms to cover the costs of publishing. The main institutions providing funding are ministries, research funding organisations (RFOs) and research performing organisations (RPOs). The article also includes a brief overview of national open access policies and gives examples of the different ways these policies are organised in different countries.

Open access book policies from research funding organisations (RFOs) ideally include a funding mechanism to cover publication costs. This article looks at the various mechanisms that are used and highlights examples of funding mechanisms that address specific challenges relating to the publishing of open access books.

European research performing organisations (RPOs) have established open access policies that also come with a funding arm. Some RPOs and their libraries commit to open access for books, often by managing dedicated open access publication funds. This article looks at various funding mechanisms and the conditions and limitations of such funding.
