I am currently conducting my first research project and I was instructed to find a data set to merge with another data set that I already have on hand. The data set I already have contains the corporation names, their file number, their incorporation date, and their file date. I am looking for a public or cheap data set to merge with the one I have on hand of Delaware corporations. I feel that since I have the file number of these corporations, that could serve as a possible merging metric. Let me know where you would look and feel free to share any advice!
