London system on Internet

I have not been able to find a lot of analysis about the London system (1. d4 followed by 2. Nf3 and 3. Bf4) on Internet as free web content. Here is what I have so far found:

* Gary Lane, Opening Lanes 57
* Gary Lane, Opening Lanes 54
* Sverre's Chess Corner is a weblog written by one of the authors of Win with the London System.
* John Watson & Eric Schiller, How to succeed in Queen Pawn Openings (pdf)

Have I missed something interesting?
