Peter Suber links to Stuart Shieber at The Occasional Pamphlet regarding the number of open access journals that charge fees. Shieber found that over 70% out of 5629 journals do not charge. The statistics were generated via a Python script and the Directory of Open Access Journals. From Suber’s commentary:
This is important for two reasons. First, it’s new confirmation that most OA journals charge no publication fees…Second, it provides a Python script (omitted here) to repeat the census at any time, allowing us to watch how the number changes over time.
