I think offering the code is a step in the right direction.  However designers are still going to have to buy a manual if they want to see section properties, use beam tables, column tables ect....   It would be nice if the "steel guys" could give design information out for free.  Maybe if the steel section properties and load tables were free more small time guys would use structural steel for smaller jobs. SJI gives a joist code with load tables away.  Manufacturered wood joist companies give away design manuals.  Steel stud manufacturers - steel joist association gives away design manuals with load tables.  These load tables promote the use of the materials for the industries they are supporting.
 
Giving away digital section properties would greatly promote the use of steel in buildings.  Why use steel beams in a residential or small commercial building when you can calculate a glulam size with a calculator and S=1/6*b*d^2 and I=1/12*b*d^3 and A=b*d.  Why use a steel beam on top of piles when you can calculate a grade beams reinforcement area with a calculator and As=b*d/m*(1-sqrt(1-2*m*Rn/fy)) & Abar=pi*D^2?  Many people do thier own spreadsheets and entering the steel section properties for lookup functions is a royal pain.  I have 7 steel manuals that probably retailed $100 a pop, I'm sure most active designers have similar numbers, I just moonlight. Haven't I been gouged enough? 
 
I reiterate offering the code free is a good move. Thank you.  A great move would be to include load tables, and hopefully give away digital section properties.  I can hardly wait to buy the new combined ASD-LRFD manual. 
 
P.S.  Why don't all the free trade supporters out there just import some data entry people and pay them to enter the database into thier spreadsheets for a few boxes of pop tarts. Where are the bodies?

>new books...

Entirely false.

We became aware that mills had changed their rolling practices and that engineers, fabricators, detailers and others were being affected by the fit-up (or lack thereof) for details with sensitivity to the sizes of the fillets. We initially attempted to reverse this change in mill practices. When that avenue was not possible, we did the advisory so you wouldn;t get caught with your pants down on a misfit.

Besides, even if I wanted to sell you a book with the new T, k and k1 dimensions right now I couldn't. Now if we had held the advisory until a new publication were available, I could see why you'd suspect what you said, but really. Come on!
