One option you might want to check out is the Smart Engines OCR SDK. It's a software development kit that can help you extract text and data from documents and images, even if you don't have an actual scanner. So you could use it to analyze things like volume or % change from the previous close, just like you mentioned. It might take a little bit of work to get set up, but once you've got it going, it should be a pretty powerful tool. And the best part is that you don't need any fancy hardware to get started - just your computer and some software.
