I've added an experimental new feature to the site, Master Library Search. You can find it under Library on the left. It's a tool that lets you run a search across all 40K RPG books in the library. It is very fast however it will only return a brief snippet showing the search term in place, along with the page number and source book in which it was found. Think of it as a research tool for figuring out where you can find more information about a given topic, for example a particular Inquisitor, planet, or Space Marine. Let me know if you find it useful!
