What are the different ways in which a journal might be able to publish in an open access format, making the journals contents free to readers?
You might consult consult John Willinsky’s “The Nine Flavours of Open Access Scholarly Publishing” in the Journal of Postgraduate Medicine. As well, the Soros Foundation has prepared a Guide to Open Access Publishing and Scholarly Societies which is “a guide meant to help scholarly societies — and small publishers — assess the options available to them for the future of their journal publishing programmes.” SPARC, the Scholarly Publishing and Academic Resources Coalition, also provides a number of resources related to open access publishing.
