I've found anywho.com to be a very useful site. Find a business, find a person, search yellow pages & white pages. Also has an option to do an advanced search. Check it out when you have time.

I am also a big user of Google's search engine. I can find any answer to any craft I am working with or simply learn something new. Recently was working on a baby afghan and couldn't remember how to cast off the project. After 4 months of knitting away, I did a Google search and there were my results. The project is complete thanks to this wonderful search engine.
