Learning SE & Scrapers!

All,

New here and new to the whole search engine and scraping bot scene. Trying to learn to be successful in gleaning info from:

  • Chamber of Commerce Lists,
  • Super Pages,
  • Yellow Book,
  • Yellow Pages.

The languages I use are: 1.) BASH, 2.) PHP
What are the opensource resources I can find to start using and gleaning the information I'm seeking?

Cheers!
