What constitutes a portfolio?

This is the question I wrestle with periodically: what's my art portfolio? Is it all of a style - only landscapes and no tarot cards, for example? Or is it anything addressing a certain topic... except I don't work that way. That would be like making one's daily journal only address one's taste in shoes.
