Open Access Articles

You've heard about Open Access journals. If you’re a student you will leave JHU at some point and that means you won’t have access to our extensive library collection. You’ll need open access then. Perhaps you're interested in Open Access as a social justice issue and wish to utilize openly available articles in your own research right now. The Library can help with that! Below are groups of tools and resources that can help you find Open Articles about a topic.

Innovation and research around Open Access, Open Data, and Open Science is ongoing, so more tools will become available with time. Check back with the library to learn more about the always-changing world of scholarly publishing. And let us know if you find other resources that point to Open Access articles.

Library Databases

Since many research funders and institutions require articles to be openly available, many library databases index Open Access journals like PLOS Biology, Nature Communications, and Sociological Science. While many databases include OA journals, they don’t all give you an easy way to limit a search to just OA articles. The databases below let you limit to Open Access articles.

  • Scopus – Once you have a result list, click the Open Access box under Access Type in the left column.
  • Web of Science – Once you have a result list, click the Open Access box under Filter by in the left column.
  • PubMed – Once you have a result list, click ‘Free full text’ under Text Availability in the left column.

Repositories

Some disciplines and funding agencies have repositories whose purpose is to openly and freely share research. These repositories offer a variety of types of articles. Without getting into a lot of detail, the article types include:

  • Preprint – an article that hasn’t gone through peer review at a journal.
  • Postprint – an article that has gone through peer review, but doesn’t include the final copyediting and page numbering from the journal. This is also referred to as the author’s final version/manuscript.
  • Version of record – the article as it appeared in the journal; it has been peer reviewed and copyedited. This is also referred to as the published article.

Two of the best known repositories are

  • arXiv is the oldest repository, hosting articles on physics, mathematics, computational biology, and other fields of research. Preprints, postprints, and published papers are available here.
  • PubMed Central is run by the National Institutes of Health. The NIH requires articles resulting from their funding to be openly available 12 months after it’s been published. The articles in PMC are either postprints or the version of record.

There are plenty of other repositories out there. Take a peek at OpenDOAR, the directory of open access repositories.
