This is actually common, at least in mathematics: Researchers simultaneously submit to a traditional journal and to the preprint server <a href="http:&#x2F;&#x2F;arxiv.org" rel="nofollow">http:&#x2F;&#x2F;arxiv.org</a>.<p>Usually I don&#x27;t have any difficulties finding contemporary papers. It is papers from, say, thirty years ago, that are usually stuck behind paywalls.
