Well this is supposed to be the CIA field manual for picking locks. I doubt this is the case, however this has some really good information in it, and will help you learn how to pick locks. I know I have another lock pick manual on here, but I like to read more than one resource, so I am passing this onto you. To view online or download click the link below.
I have located some lock pick sets as well if you are interested. I have them listed below. I located these on Amazon. Click the pictures to go to the product.
