&gt; If you aren’t affiliated with a university, scientific papers cost something like $30&#x2F;each to read.<p>It&#x27;s not <i>quite</i> that dire. DeepDyve [1], which is kind of like Spotify for academic journals, provides online access to 12 million articles from 10000 peer reviewed journals. You can buy access in blocks of 5 articles for $20, or unlimited for $40&#x2F;month ($30&#x2F;month if you buy a year at a time). They also have free 5 minute previews so if you are not on one of the unlimited plans you can get some idea if you want to buy a particular article or not.<p>[1] <a href="https:&#x2F;&#x2F;www.deepdyve.com" rel="nofollow">https:&#x2F;&#x2F;www.deepdyve.com</a>
