Searching OA and Browser Extensions

The browser extensions given below facilitate access to OA versions of paywalled resources. Along with OA browser extensions, you can also make use of academic search engines and OA specific platforms.

OA Browser extensions are reasonably effective tools to navigate through the peculiarities of OA publishing. Open Access publishing patterns often negatively affects the accessibility of OA resources. For example, the articles published in Diamond and Gold OA journals are fully accessible on journal websites. But articles in Green OA journals are not accessible at the journal website but are legally made available in other repositories through self-archiving. In the case of hybrid OA journals, only a selection of their articles is available as free. This graded access system prevalent in OA publishing reduces their accessibility. OA browser extensions help to manage this complex web of OA resources.

2) Academic search engines and networking websites

A list of academic search engines and networking websites are given under the OA section. As many academicians share their copy of articles on websites like Researchgate and academia, it is good to search these websites. It is a good practice to search in academic search engines other than Google scholar. In some search engines like Core, all search queries return with fully downloadable copies.

3) OA specific resources

Diverse types of OA resources are listed under the open access section of our library. One can start with the open access aggregators section, which mainly consist of search interfaces that exclusively return with open access resources. Apart from their search engine characteristics, OA aggregators deal mainly with current resources while general repositories consist mainly of OA resources relatively older and on the public domain.
