For example, if I were able to get an article from arXiv in a format that isn't PDF, such as LaTeX, docx, html, markdown (really anything covered by pandoc, since that's what I'm using).
From what I can tell, arXiv lets you do this if the article is under CC BY or CC BY-SA license. Does anyone know approx what % of articles on arXiv fall under those?
Also, are there any other pre-print servers which would allow this? They can cover any field and don't have to be in English.
