Open access policy developments are also showing a strong increase this quarter, with proposed mandates up by 4 to 31 and sub-institutional mandates up by 3 to 39.
Bielefeld Academic Search Engine (BASE) - 3.6 million documents growth this quarter for a total of over 47 million documents - illustrates the ongoing robust growth of the repository movement. Although only a portion of these documents are peer-reviewed open access journal articles (many are theses, increasingly research datasets and historical digitized materials), if even a tiny portion of these numbers are peer-reviewed articles that would still be highly significant - 10% of 3.6 million documents would be 360,000 documents, for example. The Social Sciences Research Network alone added 14,403 fulltext papers, and arXiv more than 22,000 documents this quarter, supporting this evidence of strong growth in open access via repositories.
Finally, a special mention to the Internet Archive - while only a small fraction of the works posted there are scholarly in nature, the capture of over 66 billion webpages this quarter for a total of over 347 billion webpages is noteworthy.
