Electronic sources that are also worth a look are

http://www.statsoftinc.com/textbook/stpowan.html

And the manual for GPower, which is free software for sample size
calculation.

http://www.psycho.uni-duesseldorf.de/aap/projects/gpower/

GPower uses effect size notation but has an effect size calculator for those
who think in terms of means and SDs.
