I don't often hype websites, but I recently have been using the Social Science Research Network for my next book and I found it astounding. The mostly free service gives you access to an amazing array of scholarly papers across the academic spectrum. For example, a search for "forfeiture" -- my legal speciality -- lists over 120 law review articles on the subject. Also, you can subscribe to various journals that strike your fancy. It is definitely worth a look.
