As with anyone in a creative media, research and resources go a long way. However, finding good Sci-Fi resources short of trawling the interwebs can be a pain the in the rear.
I've been trying to find a much more comprehensive guide to sci-fi world building (writing, art, concepts, etc), but the hard and fast rule I've discovered about the entire endeavour takes a long time, and information is located in many places, for example, TVtropes is pretty awesome for characters, common tropes, and learning how Riker manned up with some beardliness, but it lacks a lot of pretty pictures, something that is better suited to visiting great sites like the battlestar wiki and physical modeling sites.
What are some of your favorite resources?
