A few people have put together lists of all the D&D backgrounds available, but mostly they're a bit disjointed, so I thought I'd spend a few minutes categorising them and then put up that sorted list here.

We've organised it in a few different ways - firstly by lists for areas of Skills, then by Languages, and after that, you'll find a complete list of every background by its source, along with references for each.
