Type A and B Free Agents

[Bravos of Steel]

Does anyone know where I can find a list of the Type A and B free agents of the MLB for the last 4 years? I'm in the middle of conducting a senior comprehensive project at college talking about free agency and the economic implications of the MLB. I'm having a tough time finding a concrete list of these types of free agents. Anyone have any info?

USA Today posts them yearly, but AFAIK you would need to do a search for each year and then compile them together yourself. I was able to go back about 10 years and find the listings.
