This is the only article I've ever seen outlining the proper method for capturing sound with a boom microphone. It explains why a boom is the best choice for capturing live sound, what equipment and extras work best, proper holding technique and more.
Well worth a read for the producer or director who doesn't have the luxury of a pro boom operator on the set.
The article is on DV.com, which requires registration (it's free) and has enough valuable information to be worth it.
