WHAM implementation and testing

Summary
Weighted histogram analysis on monte carlo simulations
Hey all
I implemented WHAM to analyze my monte carlo simulations but I am always suspicious that it's not working properly. It gives results that makes sense most of the time but not always. The problem is that all I used is the original paper by Ferrenberg and Swendsen . I have no way of testing if my implementation has bugs.

What I'm asking is if there is a good source on the subject, a book on numerical methods that covers WHAM, maybe. Or maybe just a fool proof system that everyone knows what the results should look like for density of state and free energy based on specific pseudo random gaussians.

Suggestion. Want about 20 references on the implementation, then google search: 'WHAM algorithm'
I got several that seem to me to be very usable implementations and discussions. Plus, I cannot see the aps.org paper - paywall. Unless someone else has used this recently the paywall will be an impediment for giving you a good answer. Some folks here no longer have access.
