How many of the documents indexed in “open” repositories are in fact
freely available, rather than on “dark deposit” or otherwise
inaccessible.

What is an Immediate-Deposit/Optional-Access (IDOA) mandate, and what
is Almost-OA?

How important is the so-called eprint request Button to the success of
the IDOA mandate, and how efficacious is the Button in allowing
readers to obtain copies of items held on dark deposit in
repositories?

I offer some thoughts on these and related matters in a document that
can be accessed here:
