Readability - CD/web site

[Nelson, Julie]

My team is developing a marketing CD for our retail computer system.
We're in the initial stages of developing the layout for the main
navigation/home page.  So far, we've developed 2 different layouts.  One
has a white background, black text, navigation buttons with a red border
at the top, a few images & the very top of the page has the company &
computer system logos with a  black background behind it.  The other
layout has a black background, white text, the same company & computer
system logos with a black background & a few images.  It might just be
my eyesight, but it's more challenging for me to read the white text on
a black background than black text on a white background (or maybe this
is just what my eyes are used to).  

Do you know of any readability studies available on the web that
reference what background color/font color/font size & type is easiest
to read on a CD or web site.  Our long term goal is to include a good
deal of this content on our intranet site, so it would be helpful if the
CD & web site had a similar layout.  I'm researching this on Google, but
I thought I'd check here too.  I'm guessing I could find something on
Jakob Nielsen's site.
