Hi,

I must not be looking in the right places, but I am having trouble 
finding out about wand cores.  I've read that Ollivander only uses 
three cores: Phoenix feather, Hair from Unicorn Tail, and Dragon 
Heartstring.  I have been trying to find out what properties these 
cores add to the wands.   

If anyone know a good website or reading source, please let me know.  
Thanks for your help.
Teri
