Here are 4 options for searching for content in Open Access (OA) journals and repositories:
- Directory of Open Access Journals (DOAJ)
The Directory of Open Access Journals provides browseable lists of journals in many subjects.
OAIster is a combined catalog (in OCLC's WorldCat) of more than 25 million records representing digital resources from more than 1,100 institutions.
OpenDOAR is an authoritative directory of academic open access repositories. As well as providing a simple repository list, OpenDOAR lets you search for repositories or search repository contents.
- Google Scholar
Although it is not possible to limit search results to text materials licensed for re-use, Google and Google Scholar both index a large number of repositories and return open access results.
