Many words have been spilt over the relative merits of green and gold open access (OA). It is not my plan to rehearse these again right now. Rather, I want to explore four aspects of green OA.
First, I want to discuss how many of the documents indexed in “open” repositories are in fact freely available, rather than on “dark deposit” or otherwise inaccessible.
Second, I want to look at the so-called eprint request Button, a tool developed to allow readers to obtain copies of items held on dark deposit in repositories.
Third, I want to look at some aspects of OA polices and the likely success of so-called IDOA policies.
Finally I want to speculate on possible futures for institutional repositories.
However, I am splitting the text into two. The first two topics are covered in the attached pdf file; the second two will be covered in a follow-up piece I plan to publish at a later date.
