I'm reading quite a bit about quantum computing, especially optical quantum computing. Part of the problem is even the all-encompassing bible of quantum computing (Nielsen and Chuang, Quantum Computing and Quantum Computation) has only 10 pages on this particular physical realization. Other textbooks, by the time they're published, are already out of date. Hello, reading scientific papers!
Of course, there's a problem associated with that - results are retracted, new ones encompass and expand upon old, and papers are rather notorious for being difficult to slog through. Having slogged through a few myself, I can tell you that notoriety is well-deserved. Worse (for the self-learner), most papers are focused on only a specific problem.
All this isn't to say that papers are bad, just that sometimes other materials can be nice, and learning from just papers is difficult.
How can one find materials other than papers to learn from in a developing field?
