<p>I was searching around pubmed and reading some research papers regarding the biology of cancer, although there persists one economical conundrum: more than half of them link me to sites where I have to pay for them. Is there a way to get around this? Knowledge should be free.</p>

<p>Any paper published using NIH funds (which is virtually all biomedical sciences papers originating from the US) must now be open-access within six months of publication, although I’m not sure if papers published prior to this rule are being retroactively made publicly available.</p>
<p>On the right-hand side of the Pubmed search results, you can see a choice to search for “free full-text”. Any given abstract should also have a link to a free source in the upper right-hand corner, if it used NIH funds.</p>
<p>If you live near a university, you might also be able to visit its library and use its subscriptions to retrieve articles you want.</p>
