Open Access – CCL, CROSSREF, DOI

In the beginning – there was – Open Source Richard Stallman started the GNU project in 1983/4 To counter the rising influence of proprietary software "free as in speech, not free as in beer"

Open Access By analogy with Open Source, Open Access to the research literature entails the freedom to read, use and redistribute the published results of scholarly research and derivative works based on those publications.

Open-access (OA) literature is digital, online, free of charge, and free of most copyright and licensing restrictions. What makes it possible is the internet and the consent of the author or copyright-holder.

Green Vs. Gold

OA models reduce to one of two basic blueprints: OA archives/repositories, and OA journals.

Thirty-six Institutions — including the US National Institutes of Health, all seven UK research councils, and the European Research Council — require work they have financed to be made publicly available (usually through deposition in open-access repositories such as PubMed Central, six months after publication).

CrossRef - a linking system developed by a consortium of leading journal publishers The DOI system works like a forwarding address in the US Postal service, while CrossRef works like a huge directory of people’s addresses

DOI is like a social security number for electronic documents DOI - standardized identifier scheme maintained by CrossRef
