I don't think there are enough articles currently in existence to satisfy wikipedia. There are lots of little blurbs around the net on blogs and such but wikipedia doesn't put much stock in them. There was one print article that came out last summer but it's not archived on their site. I have a copy here but it's probably not enough:

Webcomics Review: The Book of Biff
We all have that friend who makes terrible decisions. Who manages to have horribly awful things happen to them over and over again. Who can't seem to escape disaster at any turn. There was a time once when I myself was "that guy." It wasn't too long ago, either, though thankfully I've had the good fortune to not be "that guy" for some time now.
"That guy," has a new name: Biff.
Chris Hallbeck, the author of the webcomic The Book of Biff has put out 300 single panel examples of what not to do, starring his bald Biff whose wild mustache and wilder eyebrows convey all the expression necessary to state clearly how Biff feels about his latest calamity.
Each strip is set up the same way - there's some horrible injury that is about to happen or has recently occurred to our hero, Biff. The scene clues you into a few possible reasons for this injury, but the caption is both the explanation and the punchline.
There's a whimsy and absurdity to Biff's peril in each of the strips that create the humor. For example, in his 300th strip, poor Biff has managed to awaken the evil inside his Sleeping Bag, whose angry zipper teeth have already managed to devour his lower torso. In one strip, Biff is kneeling on a lawn with a carrot, which doesn't seem terribly fraught with peril until the caption explains "As his car keys hopped away, Biff's rabbit's foot keychain didn't seem very lucky."
Hallbeck will be releasing his first book of Biff comics shortly, but for you the time is right to learn many a valuable lesson from the hapless Biff. Get started reading before you do something ridiculous - like using sausages as a chain substitute, or take a nap in a construction site.
