Crystals, Again!

Can you introduce to me some websites which give useful & practical info on crystals?I need to know how to bias a crystal correctly. I don't like those reading materials that say a crystal is an RLC and describe its internal structure. I need practical info.
Many thanks, Ali
(P.S. : Please give me some useful keywords to search the webon this topic)

Try these people:

www.quartslab.demon.co.uk

They have a section on their site which gives typical circuits with component values.
