  This document provides an updated account of material originally presented in
two field electron emission (FE) tutorial lectures given at the 2016 Young
Researchers' School in Vacuum Micro/Nano Electronics, held in Saint-Petersburg
in October 2016. The aim of the tutorial lectures was to set out modern
versions of some of the basics of mainstream FE theory. This paper indicates,
in some depth, the scope, structure and content of the tutorials, and also
where some of the related published material can be found.
