I am not sure if this is the right place to ask this question. Otherwise I would be happy to be guided to change the place of it.
For some task of data mining I need to have access to a large set of tex documents, which preferably are relevant to technical topics such as math, physics, computer science, etc.
Is there any open-source website offering this kind of documents in large numbers?
texfiles hosted at github or ask google fortexfiles. I'm afraid there is no simple way to download massive tex files from arxiv. You could try http://hal.archives-ouvertes.fr/ as well. – Clément Feb 26 '16 at 21:13.texformat, though some are.dtxetc. – cfr Feb 26 '16 at 22:49
