As you add contacts (or renew old contacts) during your job search, you should ensure that you "refresh" your relationships on a regular basis (at least every 3 or 4 weeks). This is important for everyone, but especially if you are currently unemployed. The approach for each contact will depend on the nature of the relationship. For friends, relatives and business acquaintances, it is as easy as reminding them that you're out there. If they know you they already know that you are looking for a job, so a simple email (or phone call) will usually suffice. For recruiters, a phone call (asking them if they have any leads) or an email (maybe with an updated resume or a brief on any pending interviews) should do the trick. I've included some links to networking which provide a few views/tactics for keeping your network "fresh".

• Riley Guide on Networking - This article from the Riley Guide provides an excellent review of networking. What it is, how to do it and what it isn't. The article provides a number of additional links on associated topics.
• Successful Job Search Networking - This About.com article provides another view on networking (formal versus informal) as well as a long list of additional resources. The article mentions that 60% of all jobs are filled via networking (I've heard as high as 80% as well).
• The Art of Career and Job-Search Networking - Quintcareers also has a page dedicated to networking and they also stress that this is probably the most important part of your search methods. They provide detail on networking on the web, networking groups (like Diversity, Women, Military, etc.) as well as some publications on the topic.
• The Social Network as a Career Safety Net - This NY Times article provides a real-life example of how social networking helped someone find other opportunities. While the current job market environment is likely to make it more difficult than the success of the individual in the article, it does stress the importance of networking.
