The following charts illustrate the Dramatic Growth of the Directory of Open Access Journals (DOAJ) over the past few years. In brief, from December 31, 2005 to December 31, 2008, the number of titles in DOAJ jumped from just under 2,000 to over 3,800 (almost doubled in 3 years). The increase in searchable content is even more remarkable, though! The number of journals searchable at article level more than doubled, from under 500 to over 1,300. The number of articles retrievable through these journals tripled, from about 80,000 to about 240,000. Plus, as the following charts illustrate, not only did DOAJ grow dramatically from 2005 - 2008; the growth rate also grew dramatically, by every measure examined.
