List of User-Agents (Spiders, Robots, Browser): I posted about this site two years ago, and it’s been actively maintained all this time. I’ve been checking it for the last couple days, and there are new additions every day.

I assert that this is the largest and most accurate index of User Agent strings on the Net right now (note that the front page is merely letters A through F). Does anyone know of anything better?
