=== Distribution ===
{{See also|Scientific journal#Electronic publishing}}

Like the self-archived green open access articles, most gold open access journal articles are distributed via the [[World Wide Web]],<ref name="suber overview" /> due to low distribution costs, increasing reach, speed, and increasing importance for scholarly communication. [[Open source software]] is sometimes used for [[Open-access repository|open-access repositories]],<ref name="BOAI FAQ">[http://www.earlham.edu/~peters/fos/boaifaq.htm Budapest Open Access Initiative, FAQ] {{webarchive|url=https://web.archive.org/web/20060703153606/http://www.earlham.edu/~peters/fos/boaifaq.htm|date=3 July 2006}}.

Access to online content requires Internet access, and this distributional consideration presents physical and sometimes financial barriers to access.

There are various open access aggregators that list open access journals or articles. [[Directory of Open Access Scholarly Resources|ROAD]] (the Directory of Open Access Scholarly Resources)<ref>{{Cite web |title=Welcome - ROAD |url=http://road.issn.org/ |url-status=live |archive-url=https://web.archive.org/web/20170515214110/http://road.issn.org/ |archive-date=15 May 2017 |access-date=12 May 2017 |website=road.issn.org}}</ref> synthesizes information about open access journals and is a subset of the [[ISSN]] register. [[SHERPA/RoMEO]] lists international publishers that allow the published version of articles to be deposited in [[institutional repositories]]. The [[Directory of Open Access Journals]] (DOAJ) contains over 12,500 peer-reviewed open access journals for searching and browsing.<ref>{{Cite web |last=Martin |first=Greg |title=Research Guides: Open Access: Finding Open Access Content |url=http://mcphs.libguides.com/open_access/finding |url-status=dead |archive-url=https://web.archive.org/web/20180908130856/https://mcphs.libguides.com/open_access/finding |archive-date=8 September 2018 |access-date=12 May 2017 |website=mcphs.libguides.com}}</ref><ref name="Directory of Open Access Journals" />

Open access articles can be found with a [[Web search timeline|web search]], using any general [[search engine]] or those specialized for the scholarly and scientific literature, such as [[Google Scholar]], [[OAIster]], [[BASE (search engine)|base-search.net]],<ref name="base-search">{{Cite web |title=BASE - Bielefeld Academic Search Engine &#124; What is BASE? |url=http://www.base-search.net/about/en/ |url-status=bot: unknown |archive-url=https://web.archive.org/web/20160216120421/http://www.base-search.net/about/en/ |archive-date=16 February 2016 |access-date=16 January 2018}}</ref> and [[CORE (research service)|CORE]]<ref>{{Cite web |title=Search CORE |url=https://core.ac.uk/search/ |url-status=bot: unknown |archive-url=https://web.archive.org/web/20160312113305/https://core.ac.uk/search/ |archive-date=12 March 2016 |access-date=11 March 2016}}</ref> Many open-access repositories offer a programmable interface to query their content. Some of them use a generic protocol, such as [[Protocol for Metadata Harvesting|OAI-PMH]] (e.g., base-search.net<ref name="base-search" />). In addition, some repositories propose a specific API, such as the [[arXiv]] API, the Dissemin API, the [[Unpaywall]]/oadoi API, or the base-search API.

In 1998, several universities founded the [[Public Knowledge Project]] to foster open access, and developed the open-source journal publishing system [[Open Journal Systems]], among other scholarly software projects. As of 2010, it was being used by approximately 5,000 journals worldwide.<ref>{{Cite journal |last1=Edgar |first1=Brian D. |last2=Willinsky |first2=John |date=14 June 2010 |title=A survey of scholarly journals using open journal systems |journal=Scholarly and Research Communication |volume=1 |issue=2 |doi=10.22230/src.2010v1n2a24 |issn=1923-0702 |doi-access=free}}</ref>

Several initiatives provide an alternative to the English language dominance of existing publication indexing systems, including [[Index Copernicus]] (Polish), [[SciELO]] (Portuguese, Spanish) and [[Redalyc]] (Spanish).
