Wikipedia has an excellent werewolf article that I highly suggest as background. Popular films and shows have evolved from the depiction of depraved monsters to those with a human side onto a highly sympathetic view. Click on the link to see a list of 20 essential werewolf movies.
The most surprising thing I found out with my delving into werewolves was that the silver bullet thing was a very recent invention. I guess this means I can unload my blunderbuss and cash in on all those silver dimes I had loaded up in there. Then again maybe not, see the UPDATE 22 Jun 2014: see below
An update on Vampire Hunting Kits -- although not about werewolves, they are associated with vampires, at least in Hollywood and in 21th century novels:
Oddly, there is not a great lot of literature cited about using non-projectile silver weapons such as maces, daggers or swords against such creatures. The additional interesting link is that generally the silver object in question is a personal object and a sort of ad hoc lightening rod against evil. The other thing is that the silver projectile is not grounded, in the sense of being connecting a kind of grounding circuit, which would be the case with a wielded silver mace or other silver appliance.
