Where to find info on farming crafting items

So since ive played this game and world of warcraft i found alot players run into the problem of where to farm for there Crafting skill
I have found using search engines such as Google and being specific about the your search has provided me information on to where to farm as well as hot spots to make gold now alot of the information out there is out dated but can still be helpful,along with Google,Bing,Yahoo UTUBE has some informative guides as well.

Great idea ^

or if your a higher level and you wanna start crafting, then you should go to low level areas and farm the materials!
