Parton Distributions - DIS06

TL;DR

The wide variety of different parton distributions available are outlined, and which are either necessary or suitable for use at present are highlighted.

Abstract

I discuss the current status of parton distributions. I outline the wide variety of different parton distributions available, and highlight which are either necessary or suitable for use at present.
