*PRO NERD TIP*
Today I learned about "The Wikipedia Library Card". If you've been a WP editor for >6 months, have made >500 edits, at least 10 edits in the last month, and are not blocked for being a jerk, you can access a *ton* of paywalled content for free.
ScienceDirect, AAAS, The BMJ, both APAs, EBSCO, Springer, Nature, Wiley, and many more.

All those hours in 2005 spent editing sci-fi book articles finally paying off!
