Another route to open access is the "green road": Authors self-archiving copies of their articles in open online repositories.
Authors may archive their preprints without a publisher's permission, and a majority of journals already permit authors to archive their post-prints (check SHERPA/RoMEO for policies of individual journals).
Pre-prints = the manuscript version of the paper before peer review.
Post-prints = the manuscript version of the paper after peer-review, with revisions having been made.
(These are SHERPA/RoMEO's definitions. Be aware that the definitions for these terms vary by discipline!)
Google Scholar indexes most institutional or subject repositories - allowing other researchers to easily locate this open access version of your article!
arXiv.org - is a preprint repository in the fields of physics, mathematics, non-linear science, computer science, quantitative biology, quantitative finance and statistics.
SocArXiv - a repository in the social sciences - accepts all versions of papers (not just preprints!).
AgriXiv - a preprint repository in agriculture. Established Feb 2017.
Humanities Commons (CORE) - CORE is a full-text, interdisciplinary, non-profit social repository designed to increase the impact of work in the Humanities.
Cogprints - an archive of documents in the fields of psychology, neuroscience, linguistics, computer science, philosophy, and biology.
E-LIS - hosts e-prints in library and information science.
LISSA - a new preprint server for library and information sciences!
Zenodo is a "...service that enables researchers, scientists, EU projects and institutions to share and showcase multidisciplinary research results (data and publications) that are not part of the existing institutional or subject-based repositories of the research communities."
Registry of Open Access Repositories (ROAR) - provides information about the growth and status of repositories throughout the world.
The Ranking Web of Repositories - is an initiative of the Cybermetrics Lab, a research group belonging to the Consejo Superior de Investigaciones Científicas (CSIC), the largest public research body in Spain. The Ranking of Repositories has been published since 2008 and two editions are available each year.
Repository 66 - takes the data from ROAR and OpenDOAR and overlays it on Google Maps.
An institutional repository (IR) is a digital collection of an organization’s intellectual output. IRs centralize, preserve, and make accessible the knowledge generated by academic institutions benefiting both the institution and its scholars by raising the institutional profile while also bringing broader dissemination, increased use, and enhanced professional visibility of scholarly research.
Canadian Institutional Respositories - A list maintained by the Canadian Association of Research Libraries (CARL).
If the library doesn't subscribe to a journal you need then you can request through Inter-Library Loan or... try the Open Access Button!
This tool can get you instant, legal access to research - and request research that isn't available.
The OA Button searches across repositories for legally posted author's versions of articles. If an author has not posted such a version then OA Button reaches out to them to do so!
SHARE is a higher education initiative whose mission is to maximize research impact by making a comprehensive inventory of research widely discoverable, accessible, and reusable. To fulfill this mission SHARE is creating an openly available data set about research activities across their life cycle.
BASE - The Bielefeld Academic Search Engine indexes academic open access web resources using the OAI-PMH (as above).
OpenAIRE - search across the open access contents of European repositories.
CORE (COnnecting REpositories) - aggregates repository content from all over the world.
OpenDOAR - search across the contents of repositories listed in this directory.
COAR (Confederation of Open Access Repositories) - is a young association of repository initiatives launched in October 2009. Its mission is to enhance greater visibility and application of research outputs through global networks of Open Access digital repositories.
