Online Versions & Errata
The online version differs from the hardcopy in page numbering so please refer to the hardcopy if you wish to cite a particular page.
This version corresponds to the published Cambridge University Press version, differing only in minor text details. There are some errata (in magenta) and addenda (in blue) from the published version highlighted using ampersands or plus signs in the margin text.
Please email me at david.barber@ucl.ac.uk if you find an error or have a suggestion.
