DOAJ publisher size analysis: Long-tail and APC charging trends | Sustaining the Knowledge Commons / Soutenir les savoirs communs

by : Xuan Zhao & Heather Morrison Abstract The 2021 DOAJ (The Directory of Open Access Journals) publisher group comprises a large number of very small publishers (typically with only one journal), and very few large publishers. Our purpose is to demonstrate publishers’ long-tail tendency and reveal its connection with the tendency of APC (article processing charge) or NO APC publications. As a result, we ascertain a “long-tail” of publisher size in all three groups and a “the smaller, the NO-APCer” tendency.
