Useful Resources
Top Job Aggregators:
Job aggregators pull job postings matching your search criteria from many different websites like the major job boards, direct employer career sites, staffing agency career sites, newspapers, professional association websites, industry websites, etc.
Job aggregators are great! They can save you time and show you more selection of jobs, however, there are some disadvantages too. You will likely be faced with more advertisements and have to sign up with many different job sites to apply for a job you find. Also, many of the jobs you find may be duplicates or out-dated postings that have since been removed.

Top Job Boards:
Job boards provide useful features, a consistent process, suggestions of jobs matching your background, and allow recruiters to find/contact you. I've found it most effective for job seekers to use a balance of job boards and aggregators to find/research open positions, aside from networking, of course.
