The Django Book, though great, is ridiculously out of date - the print version is written for Django 0.96, the incomplete web version is for Django 1.0, and Django 1.4 was just released.

It's a great resource, and was very useful to myself when learning Django back in the day, but the regular Django docs have far surpassed it on my made up usefulness scale.

Well I guess that makes sense, seeing that version 2 hasn't been updated since 2009. Too bad though, it is really well-written.
