It looks playable. The explorer calls it the "Snyder" variation of the Sicilian. Maybe having a name will help you find some more info...
2.b3 sicilian defense
Actually I want to thank you. Looks like a fairly rare antiSicilian that could catch a few people by surprise. Shipping costs would probably be prohibitive, but Amazon.com has a few used copies of Robert M. Snyder's book on it; as far as I know that's the only book and what with Snyder being a convicted sex offender it's probably not going to be republished. I might scour the database and see if I can find a few games...
There's an article about it by Arthur Kogan in volume 9 of Secrets of Opening Surprises, where it's called the Czerniak Attack.
Yes... it's considered to be playable. engine analysis give it a good score for white and statistics show good win rate and draw rate .
As for the books you recommended ill look it up. 
The latest of GM Ian Rogers' videos to be uploaded features Melbourne's IM Greg Hjorth winning with white against GM Robert Byrne in the 1984 New York Open. Enjoy!

There is an article on how to play against the Snyder Variation of the Sicilian right here on Chess.com. Interestingly, there has been talk, the article notes, about renaming the line The Czerniak Attack to dissociated it from Snyder because of his behavior. The article notes that anyone who plays the Sicilian a lot should be familiar with how to play against this line. I'll have to put this into my study plan:

I think he was looking for how to play against it as black, but thanks for the tip on the book. I'm a little interested it it as white.
Hey!
As a big fan of the Sicilian Defense, I find it kind of frustrating that I can't find any deep theory for 1.e4 c5 2. b3
(B20)
I get to see it very rarely when I play the Sicilian as black.
Does any of you have any videos, articles, etc… about it?
If not, I would like to create a group to study this line … anybody interested?
