Gold OA: Authors publish in an open access or hybrid journal that makes articles openly available immediately on the publisher's website. Usually the author or grant institution pays an article processing charge (APC) for this access.
Green OA: Authors can self-archive a pre-print, post-print or publisher's version in an repository such as Bates College's SCARAB. Normally publishers require an embargo of 6 months or a year on this content. Publisher policies can be found on the publisher's website or using SherpaRoMEO.
"Open Access is the free, immediate, online availability of research articles, coupled with the rights to use these articles fully in the digital environment." - SPARC
