Open access publishing is growing far faster than previously thought, according to a new report prepared for the European commission. Half of all research papers published in 2011 are now freely available online, it is claimed – nearly twice as high as previous estimates.
The research was carried out by Science-Metrix, a Canadian research evaluation firm, as part of a wider study on open access for the commission’s Directorate-General for Research and Innovation.
‘We basically took a sample of 320,000 papers from various databases and developed “harvester” software to look for the availability of articles,’ says Science-Metrix CEO Éric Archambault. ‘If it was able to download a paper it would classify it as a free article.’
