About The World Bank Open Knowledge Repository

The World Bank is the largest single source of development knowledge. The World Bank Open Knowledge Repository (OKR) is The World Bank’s official open access repository for its research outputs and knowledge products.

Through the OKR, The World Bank collects, disseminates, and permanently preserves its intellectual output in digital form. The OKR is interoperable with other repositories and supports optimal discoverability and re-usability of the content by complying with Dublin Core Metadata Initiative (DCMI) standards and the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH).

The World Bank’s new Open Access Policy (effective July 1, 2012) and the OKR both improve access for those who regularly use World Bank research outputs and knowledge products. They also increase the range of people who can discover and access Bank content—from governments and civil society organizations (CSOs), to students and the general public.

By extending and improving access to World Bank research, the World Bank aims to encourage innovation and allow anyone in the world to use Bank knowledge to develop solutions to development problems that will help improve the lives of those living in poverty.


Since its launch in April 2012, the OKR has grown to more than 13,000 research works including:

  • World Bank Group Annual Reports and Independent Evaluation Studies Books published by the World Bank Group including flagship publications, academic books and practitioner volumes;
  • All World Development Reports (WDRs) plus recent WDR background papers;
  • Journal articles published in World Bank Economic Review (WBER) and World Bank Research Observer (WBRO), two journals published by Oxford University Press on behalf of the World Bank, and the Development Outreach Magazine;
  • Accepted manuscripts of Bank-authored journal articles from selected external publishers (after an embargo period);
  • Metadata and links to Bank-authored external journal articles;
  • Serial publications (typically data-intensive outlook reports);
  • Policy Research Working Papers (PRWP)—a series of papers that disseminate findings of work in progress in order to encourage the exchange of ideas about development issues;
  • Selected other papers of high research quality;
  • Economic and Sector Work (ESW) studies—a series of analytical reports prepared by Bank staff. ESWs gather and evaluate information about a country’s economy and/or a specific sector;
  • Knowledge Notes, providing short briefs that capture lessons of experience from Bank operations and research;
  • Selected translated titles.
