Open access mandate policies showed the strongest growth in percentage terms, with a 90% increase in thesis mandates and a 61% increase in departmental mandates, 47% growth in total mandates, and 41% growth in institutional mandates. For links to full details and charts on OA mandate growth, see this post by Alma Swan. A total of 7 measures showed growth of 40% or better, including DOAJ's journals and articles searchable at article level. 7 measures showed growth of 30% or better, including the number of journals in PMC with immediate free access (37%) and the number of journals in PMC with all articles open access (34%), the number of peer-reviewed journals included in Open J-Gate (36%), and the total number of journals included in Open J-Gate (31%), the number of repositories listed in ROAR (34%), and the number of proposed open access mandates (33%). A further 11 measures were 10% or better, including BASE content providers, RePEC (both total items and items available online), and the number of documents in E-LIS and arXiv.
New this issue: historical data has been added to the full data edition (see the DGOA Dataverse to download), thanks to Tim Gray of Homerton College Library) and the Internet Archive's Wayback Machine. The show growth issue focuses on 2010 growth, and includes columns for average daily, weekly, and monthly growth for illustration purposes. New additions include Mendeley and the open data journal policies list at the Open Access Directory (the latter as a first foray into tracking the dramatic growth of open data). A first edition of The Dramatic Growth of Open Access Rationale and Methodology is now available for download from the DGOA Dataverse or for viewing as a Google Doc. For full data that is downloadable as the Dec 31 2010 full data edition or the Dec 31 2010 show growth edition, see the DGOA Dataverse at Harvard; for quick web viewing of the latest data, see the Google Docs Show Growth version. For links to all versions and commentary, see the Dramatic Growth of Open Access Series.
This post was updated Jan. 1, 2010, adding links to Alma Swan's post and the services listed below, and on Jan. 2, 2010, adding links to the Polish version created by E-LIS Editor Bożena Bednarek-Michalska, which can be found here and here. Updated again Jan. 4, adding this link to MIT stats showing the popularity of open educational resources.
A Happy New Year to everyone in the open access movement!

The open data movement is closely related to the open access movement, and of great interest and use to scholars. It is obvious that there is a lot happening; currently one of my best sources of information is Tracey Lauriault of civicaccess.ca and datalibre.ca fame. As an aside, it is a little ironic that data phenomenon / statistician Tracey is the source par excellence for qualitative information on this matter, whilst I, the critical scholar rather inclined to look with scepticism at purely quantitative research, am apparently the volunteer keeper of the quarterly statistics for the open access movement. Glen Newton points to the 70 online databases that define our planet, from Technology Review, the arXiv physics blog, as further qualitative evidence that there is a lot of quantitative data out there already.
