That $35 that scientific journals charge you to read a paper goes 100% to the publisher, 0% to the authors. If you just email us to ask for our papers, we are allowed to send them to you for free, and we will be genuinely delighted to do so. https://t.co/NHEfiOMLfG

Indeed. Before there were other sources, I emailed quite a few scientists and researchers asking for copies of papers in the late 1990s up until 2010 or so. Every single one sent me a copy that I otherwise would’ve had to spend $35+ to read.
