Where do online service reviews get their lists
I was wondering how online service review websites like google and angie's list get their listings of service providers like docters, plumbers, etc.
Are there large lists out there w/ API's?
Any insights will be helpful.

Google uses spiders to discover new URLs and index new or updated pages on sites their database already has.
Here's a good article about google's searching and discovery:
