An explanation of the principle numbering used in the online content
Each online chapter has an acronym as a unique identifier. The principles in the online chapters adopt their numbering from that acronym, so that, just as with the principles in the print book, each principle has a unique identifier.
For example, principle 12 in each of the online chapters is designated as follows: §DP.12, for the 'Defective Products' chapter; §AN.12, for the 'Liability for Animals' chapter; §EM.12, for the 'Employers’ Liability' chapter; §SD.12, for the 'Breach of Statutory Duty' chapter; §HA.12, for the 'Statutory Tort of Harassment' chapter; §WD.12, for 'The Rule in Wilkinson v Downton' chapter; §PR.12, for the 'Privacy' chapter; §PU.12, for the 'Public Nuisance' chapter; §MD.12, for the 'Multiple Defendants' chapter; and §BE.12, for the 'Beginning and End of Liability' chapter.
Where, within a print chapter, a small section of the chapter is available online, the principles in that online-only section uses a separate referencing system, whereby the principle adopts the chapter number, but uses an alphabetical identifier. For example, as noted above, Chapter 2 is a print chapter, but contains some small sections of online content. For the first online section in that chapter concerning 'Barristers', the principle in that section is numbered as §2.A. The next online section in that chapter concerns ‘Parental liability for their children’s negligence’, in which the relevant principles are numbered as §2.B and §2.C. The next online principle in Chapter 2 is under the section, ‘Parental liability to their children’, and is numbered as §2.D.
Hence, each principle in the book, whether contained in the print chapters or the online chapters, has a unique identifier which directs the reader to its precise location.
