Graphing the rise of OA journals

Heather Morrison, The newer the journal, the more likely it is open access, Imaginary Journal of Poetic Economics, December 30, 2006.  Excerpt:

Data derived from Ulrich's Periodicals Directory illustrates a strong and positive correlation between the recency of a journal's start date and open access: the more recent the start, the more likely the journal is open access. None of the titles started in the 1700's that are still active are open access. The percentage of titles started from the early 1800's to the end of 1999 never rises to the double digits. The number of titles started in 2000 rises to 19%, while the percentage of new journals classified as open access by Ulrich's is about 30% in this millennium.

It should be noted that the accuracy of Ulrich's classification of journals as open access is limited; open access journals are likely understated. It may be of interest that, according to Ulrich's, new journals have been created in 2006 which are not even online, never mind open access. 

Open data and a detailed explanation of the limitations of the data are available [here].

To its credit, Cambridge Scientific Abstracts' for-profit Ulrich's Periodicals including open access journals. The Directory of Open Access Journals provides the highly valuable service of vetting journals both for appropriate scholarly quality controls, and open access status. Surely a business relationship would make sense here? The benefits would be consistent, quality information on open access journals for Ulrich's, saving Ulrich's staff time on the vetting process; and, funds for DOAJ, to help establish a sustainable business model for this essential service....
