.	Data is from the resource website as of the date shown, except as noted otherwise. Early figures (February 2005) were recorded between January and February 2005, on dates not specified. OAIster data is from the most recent update, e.g. March 29 for March 31, 2007. Data is presented as an approximate indicator of the growth and extent of open access only. For example, the Directory of Open Access Journals, widely regarded as the most authoritative list of fully open access, peer-reviewed journals, contains just over 2,600 journals as of March 31, 2006, much less than the world's largest list of open access journals, that collected and maintained by Jan Szczepanski, over 4,705 titles as of early December 2005 - see http://oalibrarian.blogspot.com/2005/12/jan-szczepanski-collecting-for-world.html. The rate of addition of journals to DOAJ likely reflects internal staffing factors, in addition to the actual creation of new open access journals and/or conversion of traditional journals to open access. The rate of updating of websites listed is not known. The figure of 1,000 journals using OJS was added July 15, 2007, based on a report by John Willinsky July 11, 2007.

.	The author began noting and recording the dramatic growth of open access late in 2004, inspired by rather extreme understatements of the extent of open access resources and growth at that time. For early discussion on this topic, see the SPARC Open Access Forum https://mx2.arl.org/Lists/SPARC-OAForum/List.html.
