Scientific classification sources

[LaQuita Beth Dinkins <ldinkin@TENET.EDU>]

I'm needing a good resource on scientific classification--info
on kingdom, phylum, class, order, family, genus, & species.
When our science classes do research on this, it turns into a
real treasure hunt using encyclopedias and Audobon books.
I have asked our science teachers about this and they haven't
been able to come up with anything.  Is there a better source
you could recommend?  Thank you very much!
