Contracts

Resumes. I thought these things were hard enough when you worked at a place full-time for a year. How do you update your resume to include a 2-month contract job? How do you update it to include simultaneous part-time contract jobs? What do you tell a potential employer when you have a job you started this morning on your resume? Once you move beyond the magical one-page limit (because it leaves huge gaps in my resume, at least), how do you avoid listing every single job you've ever had?
