So Roger there is no doubting your credentials and the research material you have. I took your original question to be is this a viable "business". So what we personally think about you and the work you have produced doesn't matter. So I will continue to play devils advocate vs simply say great idea you should do it.
Are you planning on making this a free site to browse the info and only have to pay to get a pdf of the data? Or are you talking about making a member only pay site to even see the info?
Would it be nice to have to only got to one place instead of several for documents - yes. But other than offering a one stop shop for the data what extra are you offering that could not be had from going to multiple sources that have the original documents?
Are you going to continue to add new documents or updated info to the database (example Fraser) if/when new info comes out that you didn't have? Or is it simply the data/research you currently have and not updating it with new information on topics you may not currently be researching?
Finally, unless you are just going to throw up website willy-nilly have you created a business plan? If not, I would recommend you do. You should be able to easily determine your needed volumes and rates necessary to break even during the plan creation. Also, instead of all this hassle, why not just start charging those people/groups who ask you for data/research right now?
The question isn't would people pay for this data from you. Some would. Some wouldn't. Of those that would, it would mainly be one time shoppers I imagine.
The question is sustainable traffic. Is what you provide going to bring enough paying traffic to sustain this site and cover costs? I would say not likely.
100% the same. I prefer the books/documents in my library vs the internet for reference.
