I looked for the number of full-text OA documents and the like available in the repositories, and the date for the numbers in question. ...
The repositories' slope, a measure of how fast they have grown on average over their lifespan, is plotted against the start dates ...
Summary: Re: Deblauwe, F. (2008) OA Academia in Repose: Seven Academic Open-Access Repositories Compared: A useful way to benchmark OA progress would be to focus on OA's target content -- peer-reviewed scientific and scholarly journal articles -- and to indicate, year by year, the proportion of the total annual output of the content-providers, rather than just absolute annual deposit totals. The OA content-providers are universities and research institutions. The denominator for all measures should be the number of articles the institution publishes in a given year, and the numerator should be the number of articles published in that year (full-texts) that are deposited in that institution's Institutional Repository (IR). (If an institution does not know its own annual published articles output -- as is likely, since such record-keeping is one of the many functions that the OA IRs are meant to perform -- an estimate can be derived from the Institute of Scientific Information's (ISI's) annual data for that institution.)

The open access movement:
Putting peer-reviewed scientific and scholarly literature
on the internet. Making it available free of charge and
free of most copyright and licensing restrictions.
Removing the barriers to serious research.
I recommend the OA tracking project (OATP) as the best way to stay on top of new OA developments. You can read the OATP feed on a blog-like web page or subscribe to it by RSS, email, or Twitter. You can also help build the feed by tagging new developments you encounter.
