I don't understand the question. Are you asking "how to find quality links" for your website? If so, get on Google and start searching. If you have a website that sells coffee, search Google for Coffee Dirctories or websites about coffee. then contact the site owner (or see if they have link submission guidlines) about a link trade, or advertising information. If you have a website about medicare information, search Google for websites that act as directories that contain websites with information about medicare? Make sence? The most important thing to know right now is to stay away from companies that try to sell "10,000 links to your website of only $29.95 per month". Also, see the directory and link building section of this forum.
I suggest doing what Sundevil said. Search yahoo, google, msn for the keywords that you wish to rank for and contact webmasters of sites that appear in the top 50 results.
