Many open access research articles are available, although not always easy to find. This is changing thanks to the efforts of the following sites. Each site has a search feature that can be used to find research of interest.
- Digital Commons Network
- Directory of Open Access Journals (DOAJ)
- Google Scholar
- Hathi Trust
- Public Library of Science (PLOS)
- Scientific Research Publishing
- Social Science Research Network
