This simple chart illustrates the near doubling of the growth rate of the Directory of Open Access Journals from 2007 to 2008, from an average of more than 1.2 new title per calendar day, to an average of 2.2 new titles per calendar day.
As further illustration of the growth rate of DOAJ: as of today, DOAJ includes 3,587 journals , and has added 63 new titles in the last 30 days, more than 2 new titles per day (and it’s August!). Since September 30, 2007, DOAJ has grown from 2,846 titles, an increase of 741 titles in 11 months, or 330 days at 30 days/month, for an average net growth of 2.2 titles per day. In the September 30, 2007 Dramatic Growth of Open Access update, I noted a growth rate of 1.2 titles / day for DOAJ over the previous year.
Now, if you’re like me and need a visual aid to understand the rate of growth in absolute number of titles versus rate of new titles, check out this chart I tossed together from Heather’s data:
