Alice Meadows has published "Flipping, not Flopping: Converting Subscription Journals to Open Access" in The Scholarly Kitchen .
Here's an excerpt:
The question of whether—and, if so, when and how—to 'flip' a traditional, subscription-based journal to open access (OA) is one that comes up time and again in meetings with our society partners. It's also something that funders sometimes like to suggest as a quick route to a more open world—"Why not just convert all your journals to OA?" they ask.
