1. A functional resume. This is a little different from what Career Services advises. I recommend it because it emphasizes your skills, and gives you a chance to sell these skills to an employer right out of the box. You can find a model of this resume in the Career Tips handouts on the right hand sidebar of this site. Remember that your campus media work is not an "activity," but "experience," and get it up high.
2. A solid LinkedIn profile. Spend some time on this. (You'll find LinkedIn advice in this blog, read through the posts!) Develop a well-written and edited summary with lots of keywords, and an emphasis on your solid skills and results. Get a good professional photograph. Talk to profs or former employers or internship supervisors and ask to Link In with them, and ask if they'd provide a recommendation for you on your LinkedIn profile.
3. A digital portfolio with links to your published work. You can do this with a simple Wordpress site, or with a site like Pressfolios. Be sure to put a LinkedIn badge on your page. Get the code for your profile at LinkedIn.com/profiles/public-profile-settings. Your badge size options and the code is in the lower right hand column.
4. PDF's of ten of your best clips, in case an employer wants them printable. These should include breaking news, enterprise stories, features---a range of your best work--stored on Dropbox so you can access them anywhere and e-mail or print them as needed. This gives you the flexibility for employers who want hard copy.
5. Business cards. You can get these at Staples, or online at Vistaprint.com. On this card, you should have the LinkedIn address and your portfolio address.
Here's a post from Romenesko about how graduating journalism students should present their clips to potential employers.
