A list of LinkedIn industries, in various formats.
The LinkedIn API does not appear to provide an endpoint for retrieving a complete list of industries that appear in job entries. If you want such a list for your app, you'll need to keep it handy in your local codebase. So here ya go.
linkedin_industries.csv is manually copy/pasted from LinkedIn's official list and then exported to JSON, YAML, and Ruby source. Yeah, it'd be better to automate the data-scraping, but I'm led to believe that the content doesn't change all that often.
For all you Rubyists out there, a gem is also available.
The most recent version of this list is available on Github. If you have updates, please send a pull request my way.
