Yahoo!7 Search helps you find local business listings in two quick ways.

Search Results Page
You can switch from web search to Local search by clicking the “Local” link above the search box. This takes you to a Local results page that brings together the best of Yahoo!7 Search and Yahoo!7 maps . For example, a Local search can pin point the names and numbers of local bookstores as well as public transportation routes, ATMs, and any museums near by. Use the options in the left column of the Local results page to refine your search further.

If you don't specify a new locale for your search, Local uses the last location you searched. To return to web search use the Yahoo!7 link in the upper-left corner on the Local search results page.

Yahoo!7 Search start page
You can also search Yahoo!7 Local from the Search start page. Go to the main Yahoo!7 search page and click the "Local" link above the search box. Enter the business name or category and the location. You'll get the full listings that match your search terms.
