Probably not in so many words. An electronic resume is simply any form of resume that is sent or used in conjunction with computers. So, you're changing jobs and brushing up your resume. Yes, most definitely. Just like employers today expect you to customize your resume and cover letter for their opening, they also appreciate candidates who customize their resume for their technology.

If you're a Human Resources professional on the receiving end, trying to decipher every document format known to man is more trouble than it's worth. And email is just one form of the electronic resume. Like every other department within a company, the Human Resources departments are becoming more and more automated. It's not necessary to go out and spend hundreds of dollars having someone write a separate resume. The main difference between a regular resume and an electronic resume is simply formatting.
