Professional networking site LinkedIn added five new category sections to its user profiles: Publications, Languages, Skills, Certifications, and Patents.

More details from a post on the LinkedIn Blog by associate product manager Aaron Bronzan:

If you are an author, an academic professional, or a researcher, your body of publications helps define you as a professional. With the Publications section, you can add your published work to your profile.

Do you speak multiple languages? Now professionals with language fluency can indicate their expertise with the Languages section.

List your skills, areas of expertise, and proficiencies on your profile with the Skills section.

The Certifications section allows you to list the certifications, licensure, and clearances that you have attained.

Show off your inventions with the Patents section, which lets you list both granted and pending patents.
