A 2015 second edition of my 1982 Lecture Notes in Chemistry volume has been published. Its title is: "Bonding in Electron-Rich Molecules Qualitative Valence-Bond Approach via Increased-Valence Structures", and is volume 90 in the Springer Lecture Notes in Chemistry series.

As was done in the first edition, it focusses attention on Pauling "3-electron bonds" and singlet diradical Lewis structures, as well as the familiar Kekule-type Lewis structures, as components of increased-valence structures.
