High-energy physics. Yes, literally <i>every</i> paper that&#x27;s worth your time is on arxiv first. The only time anyone reads from an actual peer-reviewed journal is when something that was on arxiv eventually gets published (you know, a year later) and might have minor corrections. And I don&#x27;t know a single person that picks up journals for those crucial papers that were never posted to arxiv.<p>What&#x27;s the point of &quot;formal peer-review&quot;, anyway? If you&#x27;re in the community you talk to your colleagues about what&#x27;s on arxiv and you know what&#x27;s good and what isn&#x27;t. You don&#x27;t need a journal to tell you.
