This open source tool was funded by Public Library of Science, Jisc, Open Society Foundations, Mozilla Science and Crowdfunders.
- Unpaywall - This tool searches and finds full-text research papers as you browse. Data is sourced from open-access repositories including institutional repositories and reprint servers. Just download the Chrome or Firefox extension and the tool will do the rest. This open source tool was created by Impactstory with grants from the National Science Foundation and Alfred P. Sloan Foundation.
The bulk of the content on Scopus is peer-reviewed journals which are selected according to our content coverage policy. Over 3,600 peer-reviewed titles are full open access titles (according to DOAJ and/or ROAD).
"Started in August 1991, arXiv.org is a highly-automated electronic archive and distribution server for research articles. Covered areas include physics, mathematics, computer science, nonlinear sciences, quantitative biology, quantitative finance, statistics, electrical engineering and systems science, and economics. arXiv is maintained and operated by Cornell University with guidance from the arXiv Scientific Advisory Board and the arXiv Member Advisory Board, and with the help of numerous subject moderators."
Note that arXiv content is moderated, but not (generally) peer reviewed.
Identifying Open Access Journals

"The SCImago Journal & Country Rank is a publicly available portal that includes the journals and country scientific indicators developed from the information contained in the Scopus® database (Elsevier B.V.). These indicators can be used to assess and analyze scientific domains. Journals can be compared or analysed separately."
