A recent comment on one of Steve Pavlina's forums indicated that the information covering Biphasic Sleep is somewhat lacking. Sadly, it is; these however are good places to get started :

The power of the Sleep Cycle

This is the article that helped to establish by basic sleeping times and their split. Although originally written in 2003, it was updated in 2005 and contains some good information.

Eric has recently switched over to a biphasic sleep schedule, and is posting brief updates of the experience on his site.
Biphasic Sleep FAQ

This covers several of the common questions and answers for biphasic sleepers (Devin follows a similar split to my own).
Cutting out the crap
Joesph Young
Whilst I don't agree with a couple of statements in this article, the overall ideas are interesting (alternative viewpoints always are). In particular, this strikes me as odd :
Take a step back and realize that if you are to adopt a biphasic or polyphasic sleep system, you are asking yourself to make a HUGE change in your life. I mean HUGE - on par with buying your first house, or deciding to go strictly vegetarian, or even taking care of your first child.
Personally, I didn't find the change all that dramatic (in a negative way - there were plenty of benefits, and they keep growing all the time). It would surely depend upon the lifestyle of the person making the switch; immediately prior to the change.
In my case, I've essentially just lopped a little off the end of my monophasic sleep (I used to wake up around 9am, now it's around 7am, and moved it to a 75 minute nap start around 7:30pm. The core sleep now begins around 2am; when I was monophasic I started around 1:00-1:30.
However, the article - in fact the entire biphasic sleep category on that site - is still a good read.
Finally, I humbly offer up several of my own pieces on biphasic sleeping :
- Biphasic Sleeping update
An update a little over two months after the switch to biphasic sleeping. - Napping in the afternoon
Results of a week-long trial of switching the nap from early evening to mid-afternoon. - Biphasic Sleep: 30 day summary
This post takes a comprehensive look at the initial 30 day trial. It was a very rewarding experience. This post also contains links to journal entries from each day of the trial period. - First week of workouts on biphasic sleep
Exactly what it says on the tin. - 30 days of biphasic sleep
Initial plans for the trial, and a brief discussion of the original motivation for the change. - Power of the 90 minute nap
The post which started it all.
