As part of a study I'm working on, I've built a multitude of web scrapers to download job listings from a group of Fortune 500 companies. The listings are saved in plaintext, separated by industry, company, and job, are generally clean, and contain job titles, descriptions, qualifications, responsibilities, and locations.

I figure these files could be used for machine learning, further studies on the language used in job listings, or by people looking to build intelligent job search bots. The cache is large -- >20mb I believe. Where would be the best place to offer the files (in terms of visibility and usefulness)? Is this something that is commercially valuable? If so, where are collections like these usually sold?

Thanks!
