One can manually browse through scholarly publishers' websites and see the number of journals they publish, such as:
- Elsevier: ca. 4.330 journals
- SAGE: ca. 1.200 journals
- Inderscience: ca. 430 journals
- Cambridge University Press: ca. 380 journals
- Emerald: ca. 350 journals
- Hindawi: ca. 230 journals
- MDPI: ca. 200 journals
However, a manual search risks leaving out certain publishers, is prone to mistakes, and is quite time-consuming.
I would thus like to know: Is there already a comprehensive list of large academic journal publishers ordered by the number of journals they publish?
EDIT: I am not intending to crowdsource a full list here; such an approach would be flawed as well. The background for my question is that I would need precise data about academic journal publishers for a specific analysis, and before I go on to design a time-consuming data-collection method, I wanted to ask this question here.
