To set the scene for Dodgson's own work on mathematics Keith Hannabuss explores the Oxford that Dodgson's father would have known and explains the sort of changes that were going on at the time.

The diversity of Dodgson's work is revealled by a selection of papers now at Princeton University including: 'The Introduction of a 4th Co-ordinate into Algebraic Geometry', 'A Pound of Small Shot exposed more Surface Area than a Pound of Large Shot', 'A Short Method of Squaring a Number', 'Find Two Pairs of Squares whose Sums are Equal', 'To find the Number of Different Cubes that can be formed with Six Equal Squares of Different Colours'

Iain McLean will present Dodgson's work on the axiomatic theory of voting. This was completely unknown until rediscovered by Duncn Black in the 1950s. Part of which, on Proportional Representation systems, was not understood for another 30 years.

Charles Dodgson devised a series on precise procedures for solving certain types of logic problem. By studying the evolution of these methods we can get a better understanding of the way in which Dodgson worked.

In spite of its light-hearted title, 'Pllow Problems' is a collection of serious mathematical problems devised by Charles Dodgson. Very little attention has been paid to this book, yet it reveals much about the level and diversity of Dodgson's work.

David Singmaster adopts the role of mathematical historical detective in order to trace the background of this particular mathematical puzzle and explores Dodgson's own version of it.
