If you regularly refine your LinkedIn profile, you will have an up-to-date resume online.
LinkedIn also lets you put your online information into a stylish PDF print-ready resume you can share with other people.
To generate a resume using your LinkedIn profile, visit the LinkedIn Resume Builder and follow the steps outlined there. Note that you can maintain different versions of your resume using this tool while keeping the content consistent with your LinkedIn profile.
Oct. 26 update: Resume Builder hasn’t been available at all this week. I sent LinkedIn a message and was told “The ticket reference number for your question is: #121026-006553.” Hopefully this issue will be resolved soon.
