Here are some online resources I find useful for empirical work. Nowadays, it is quite easy to spot a myriad of similar things out there. But to me, many are of poor quality, some even misleading and may result in bad habits. Indistinguishable names also makes Googling hard. This motivates me to constantly maintain this list so that I can consult them anywhere anytime without taking up memory. Should you discover something or have any sort of thoughts, I will be really happy to know.
