The Directory of Open Access Journals was established in 2003 at Lund University Libraries as a list of 300 open access journals. Since then the index has grown to over 18,000 titles from 130 countries, and DOAJ is now an organisation with an ambitious mission: to increase the visibility, accessibility, reputation, usage and impact of quality, peer-reviewed, open access scholarly research journals globally, regardless of discipline, geography or language. As DOAJ approaches its 20th year, how is it adapting to a changing open access landscape? How can it contribute to a diverse open access future?
