Gold Open Access 2017-2022: Articles in Journals (GOA8) is now available in print book, PDF ebook, and dataset forms. The print book–a 6×9 trade paperback with color graphs–is $11.50 (or the nearest equivalent in other currencies supported by Lulu), of which I receive a stunning $0.24. The PDF ebook and dataset are both free, and all versions are CC-BY.
As usual, all links are available at https://waltcrawford.name/goaj.html, or you can use these direct links:
Next, some time in July, Diamond OA 2023: The World of No-Fee Open Access Publishing, covering the same years and the no-fee portion of the dataset–but with a little lightweight new research added to give some sense of how such journals are funded (when they’re not directly from universities or societies).
