Wouter has today posted a Powerpoint with a slide showing the number of Dutch open access articles and reviews indexed in Web of Science, 1995-2015…

It’s good to see coverage is ‘on the up’, but it seems that open access journal content from the Netherlands is currently indexed in WoS at just 11%. This is another indication of the low level of OA journal article discoverability in big commercial databases, and a reminder that the coming Google Scholar / Web of Science combo interface won’t make Scholar a one-stop shop for finding open access articles.
