Gold Open Access materials are made available by the publisher on their website. Open Access journals are fully Gold publications meaning anyone with an internet connection will be able to access all of the research published.
The Gold route is associated with APCs or article processing charges but not all Gold journals charge for publication.
Green Open Access materials are made available by the author through deposit in an Open Access repository in addition to traditional publication by the publisher.
This means authors may need to know what re-use rights the publisher assigns to them and may need to take steps to ensure that they retain the copyright of their work and are not required to sign it over to the publisher.
Self archiving is a method authors can use to make sure that as many people as wish to can view their research, not just those who have access to subscribed content.
Self archiving involves the author making their version of the work available online, through a website or a repository. At Teesside we have an institutional repository, TeesRep, which authors can use to deposit the peer reviewed version of their work. There are also numerous geographic and subject repositories in which authors can place a copy of their work.
In a Jisc survey of academic publishers in 2003 90% allowed some form of self archiving.
Subscription based journals will offer a Gold option for authors who publish with them. Many government research funders require the outputs of their funded research to be made available through OA therefore publishers need to offer this option if they want to continue to publish government funded research.
The fees for Hybrid Gold can be high however many funders will allow additional funds to facilitate making the work accessible.
