Open source scientific information

A series of links to open access journal repositories and other freely available scientific publications, data resources, news services, etc.

Open access publications are available to anyone, anywhere with a suitable internet connection.

The trend for publishing open access papers has increased year-by-year since it took off around 2000. A 2009 report in Science demonstrates that articles that are published via open access are twice as likely to be cited by scientists in developing countries, although this effect was less apparent in those countries with limited internet connectivity. A report in SciDev.Net also highlights the fact that publishing scientific work through open access outlets also makes the work more readily available to other interested parties, including the media, government officials and students.

Nevertheless, open-access publishing has recently been critized because of the poor reviewing processes of some journals, or dubious charging practices put in place by some publishers (see: Butler-Adam J. Dealing with ‘open access’ demons. S Afr J Sci. 2014;110(5/6), Art. #a0070, 1 page.

With the benefits of open-access publishing in mind, and allied with TWAS’s goal of making scientific information more readily available throughout the developing world, this page provides links to a number of open access resources that we trust.

Another resource, supported by the intergovernmental organization COMSATS (Commission on Science and Technology for Sustainable Development in the South), is Science Vision, a journal highlighting important scientific and technological developments that have a bearing on socio-economic conditions.

An article from The Scientist, provides links to legal methods to retrieve paywalled articles for free:

  • Open Access Button
  • Unpaywall
  • Kopernio
  • How Can I Share It is a website of the International Association of STM Publishers that provides information about publishers’ self-archiving policies, including a tool for researchers to enter their papers’ digital object identifiers (DOI) and automatically see a list of places where specific versions can be posted.
  • CHORUS is working to make papers that are required to be shared by funders (such as the National Science Foundation) automatically available on publishers’ websites.


For the most complete listings of open access journals, please visit:

  • Directory of Open Access Journals. This service covers free, full text, quality controlled scientific and scholarly journals.
  • Directory of Open Access Repositories. OpenDOAR is an authoritative directory of academic open access repositories.
  • The arXiv e-Print Archive, hosted by Cornell University Library, also provides open access to more than 1.9 million e-prints in physics, mathematics, computer science, quantitative biology, quantitative finance and statistics.
  • The bioRxiv pre-print server for biology is hosted by Cold Spring Harbor Laboratory.
  • PeerJ also provides open access pre-print and articles in the biosciences.
  • The UNESCO-hosted Global Open Access Portal (GOAP) presents a current snapshot of the status of Open Access to scientific information around the world.


For individual researchers in developing countries:

  • The electronic Journals Delivery Service (eJDS) allows individual scientists at institutions in least developed or low-income countries to access current scientific literature, mainly in physics and mathematics. The service requires registration and is cost-free. The articles are sent as email attachments, which can be useful in low-bandwidth situations. eJDS is run by the Marie Curie Library at ICTP in Trieste, Italy, with the participation of leading scientific publishing societies and companies.


For institutions in developing countries:

The Research4Life consortium provides access to eligible institutions through four subject-wise portals:

  • HINARI provides access to up to 21,000 journals and up to 69,000 e-books in the biomedical and health literature;
  • AGORA provides access to up to 15,500 key journals and up to 48,000 books in more than 115 countries;
  • OARE provides access to more than 2,900 journals in the environmental sciences;
  • ARDI provides access to about 30,000 journals, books, and reference works for 120 developing countries;
  • GOALI, the Global Online Access to Legal Information was launched in March 2018 by the International Labour Organization to provide free or low cost online access and training to law and law-related content to eligible institutions in developing countries.

Thanks to the consortium, journals listed on these sites that are not usually 'open access' are made available for free to eligible institutions.

Note also that BioMed Central has an Open Access Waiver Fund and subsequent no cost policy that supports scientists working in lower-middle-resource countries who wish to publish in BioMed Central journals.
