First, you should think of having two versions of your portfolio, a hard copy and an online one.
For the online portfolio: before you set it up, investigate yourself using online search engines and make sure to clean up your online image. Pictures of yourself chugging beer or dancing in a wet T-shirt at Spring Break won't impress employers. Next, create a professional web page, perhaps on a site like LinkedIn, that will contain more elaborate versions of your hardcopy portfolio with active links to relevant materials.
Print portfolio: The two major parts should consist of:
1) Things you can leave with contacts, including business cards containing your cell phone number, email, and web page address, copies of your resume, and perhaps a few samples of your work.
2) Things you can show to potential employers, and copy or email as needed:
- Academics: diplomas, transcripts, awards
- Examples of your work or links to websites of previous employers
- Copies of reference letters or email addresses of references
- Information about extracurricular or community service activities that might be relevant to potential jobs
