This is an area of OA growth very much concentrated in repositories rather than OA publishing.

This is covered in my description of method (link from the main series post, also an appendix in my dissertation.<br /><br />However I argue that the sheer size of the increase strongly suggests strong OA peer reviewed article growth. With 9 million documents added last year, if OA scholarly works were 1% of this that would still be close to a hundred thousand items.

Either the harvested record contains only metadata of a publication or the access to the full-text content is restricted.<br /> <br />This, of course, is due to the frustrating limitations of the current repository metadata and OAI-PMH protocol. There is no reliable way to tell which records are connected to full-text or open access items.<br /><br />Also, if you concentrate strictly on scholarly open access publishing, you should note that both BASE and the sources it is harvesting contain many kinds of non-scholarly materials. Unfortunately the most common document types at BASE are &quot;text&quot; and &quot;unknown&quot;, which is not very informative. <br /><br />What I&#39;m trying to say (I guess) is that you should be very careful in comparing different numbers gathered from multiple sources.Jyrki Ilvahttp://blogs.helsinki.fi/digikirjasto/noreply@blogger.com
