As one of the other replies has stated that trimming the older stuff from your resume can help. I took a variation on that by going into detail with jobs for the last 10 years or so and having a simple list of other places I've worked and what the job titles were. There's also a linkedin url which has the expanded version if the reader is interested in going back more but it let me keep my resume to a single page, single sided, summery of the "professional me".
