Conference proceedings and talks on a CV? I come from a multidisciplinary background, mostly biostatistics and bioinformatics. I'm currently updating my CV to apply for a post doc and I'm wondering how do people include conference proceedings and invited talks in a CV.

In my case, I have two type of abstracts: 
- peer-reviewed conference proceedings which are published in journals,
- peer-reviewed abstracts accepted in national or smaller conferences which aren't published. 

Should I make a distinction between these two types of abstracts? How do you separate abstracts selected for an oral comunication and/or poster and invited talks?

I used to have a section named Conference contribution and three subsections Invited talk, Oral communication and Poster but I'm not sure about this format and I'm wondering whether it's relevant to add this information or if I should filter more. Also, do people include all abstracts or only the first author?
There is a little bit of variation depending upon the discipline, but generally the convention is along the lines of the following:


  CONFERENCE PROCEEDINGS
  
  Invited Talks
  
  Unsolicited presentations (ex. keynotes) where you are invited by the organizers.
  
  Papers
  
  Complete manuscripts that are published in proceedings and indexed by relevant databases.
  
  Abstracts
  
  Short (i.e., 250 words) or possibly extended abstracts intended to describe the talk.
  
  Posters
  
  Any poster presentations, these may be eliminated by senior scholars.


Generally the rule of thumb is that the section is organized by most prestigious (i.e., invited talks) to least prestigious (i.e., posters). When applying for an academic position this section should be as complete as possible as well. Additionally, it may include notation indicating you are the presenter if you are not the first author.
