The simplest definition of "Green Open Access" is open access delivered by repositories, through a process of self-archiving.
WPSphere is the University's new institutional repository. Faculty are invited to share their scholarly and creative work through WPSphere by contributing article pre-prints and post-prints, conference papers and presentations, open educational resources, data sets, and other materials. Please contact Annamarie Klose Hrubes, Digital Initiatives Librarian, for more information about WPSphere.
Support for self-archiving takes a variety of forms, but the most common means is the creation of institutional and subject-oriented open access repositories. Here is a list of portals to some of the major repositories around the world:
According to the Budapest Open Access Initiaitive (2002), a key method of making scholarly research more accessible is through the practice of self-archiving: "To self-archive is to deposit a digital document in a publicly accessible website. Depositing involves a simple web interface where the depositer copy/pastes in the "metadata" (date, author-name, title, journal-name, etc.) and then attaches the full-text document. Self-archiving takes only about 10 minutes for the first paper and even less time for all subsequent papers. Some institutions even offer a proxy self-archiving service, to do the keystrokes on behalf of their researchers. Software is also being developed to allow documents to be self-archived in bulk, rather than just one by one."
What is the purpose of self-archiving?: "The purpose of self-archiving is to make the full text of the peer-reviewed research output of scholars/scientists and their institutions visible, accessible, harvestable, searchable and useable by any potential user with access to the Internet. The purpose of thus maximizing public access to research findings online is that this in turn maximizes its visibility, usage and impact -- which in turn not only maximizes its benefits to researchers and their institution in terms of prestige, prizes, salary, and grant revenue but it also maximizes its benefits to research itself (and hence to the society that funds it) in terms of research dissemination, application and growth, hence research productivity and progress."
