What is Open Access?
"By 'open access' to this literature, we mean its free availability on the public internet, permitting any users to read, download, copy, distribute, print, search, or link to the full texts of these articles, crawl them for indexing, pass them as data to software, or use them for any other lawful purpose, without financial, legal, or technical barriers other than those inseparable from gaining access to the internet itself."
There are two main approaches to providing open access:
The Green Road: Self-archiving through the direct deposit of scholarly works into a repository such as eScholarship@Morgan (part of MD-SOAR). It is not a publishing method and its express purpose is to make information as accessible as possible. Self-archived works may be published, to-be-published (pre- and post-prints), or unpublished (many theses and conference papers).
The Gold Road: Publishing in open access journals which offer full text access for free to the public.
